How to Create Presentation Slides With HTML and CSS

As I sifted through the various pieces of software that are designed for creating presentation slides, it occurred to me: why learn yet another program, when I can instead use the tools that I'm already familiar with?

We can easily create beautiful and interactive presentations with HTML, CSS, and JavaScript, the three basic web technologies. In this tutorial, we'll use modern HTML5 markup to structure our slides, we'll use CSS to style the slides and add some effects, and we'll use JavaScript to trigger these effects and reorganize the slides based on click events.

This tutorial is perfect for those of you new to HTML5, CSS, and JavaScript, who are looking to learn something new by building. After this you could even learn to build an HTML5 slide deck or a dynamic HTML with JavaScript PPT . The sky is the limit. 

Wondering how to create an HTML slideshow? Here's the final preview of the presentation HTML tutorial slides we're going to build:

Have you checked out HTML tutorial slides? It's a good example of HTML PPT slides for download.

Let's begin.

1. Create the Directory Structure

Before we get started, let's go ahead and create our folder structure; it should be fairly simple. We'll need:

• css/style.css
• js/scripts.js

This is a simple base template. Your files remain blank for the time being. We'll fix that shortly.

2. Create the Starter Markup

Let's begin by creating the base markup for our presentation page. Paste the following snippet into your index.html file.

From the base markup, you can tell that we are importing Font Awesome Icons, our stylesheet ( style.css ), and our JavaScript ( index.js ).

Now we'll add the HTML markup for the actual slides inside the <div> wrapper:

We have seven slides in total, and each slide is composed of the heading section and the content section.

Only one slide will be shown at a time. This functionality is handled by the .show class, which will be implemented later on in our stylesheet. Using JavaScript, later on, we'll dynamically add the .show class to the active slide on the page.

Below the slides, we'll add the markup for our slide's counter and tracker:

Later on, we'll use JavaScript to update the text content as the user navigates through the slides.

Finally, we'll add the slide navigator just below the counter:

This section consists of four buttons responsible for navigating left and right and switching between full-screen mode and small-screen mode. Again, we'll use the class .show to regulate which button appears at a time.

That'll be all for the HTML part. Now, let's move over to styling.

3. Make It Pretty

Our next step takes place within our stylesheet. We'll be focusing on both aesthetics and functionality here. To make each slide translate from left to right, we'll need to target the class .show with a stylesheet to show the element.

Here's the complete stylesheet for our project:

4. Enable Slide Navigation

Whenever we click on the left or right icon, we want the next slide or previous slide to appear. We also want to be able to toggle between full-screen mode and small-screen mode.

Furthermore, we want the slide's counter to display the accurate slide number on every slide. All these features will be enabled with JavaScript.

Inside js/index.js , we'll begin by storing references to the presentation wrapper, the slides, and the active slide:

Next, we'll store references to the slide counter and both of the slide navigators (left and right icons):

Then store references to the whole presentation container and both button icons for going into full screen and small screen mode:

Now that we're done with the references, we'll initialize some variables with default values:

screenStatus represents the screen orientation. 0 represents a full screen mode, and 1 represents a small screen mode.

currentSlideNo represents the current slide number, which as expected is the first slide. totalSlides is initialized with 0, but this will be replaced by the actual number of our slides.

Moving the Presentation to the Next and Previous Slides

Next, we'll add click event listeners to the left button, right button, full screen button, and small screen button:

We bind corresponding functions that will run when the click event is triggered on the corresponding element.

Here are the two functions responsible for changing the slide:

In the function moveToLeftSlide , we basically access the previous sibling element (i.e. the previous slide), remove the .show class on the current slide, and add it to that sibling. This will move the presentation to the previous slide.

We do the exact opposite of this in the function moveToRightSlide . Because nextElementSibling is the opposite of previousElementSibling , we'll be getting the next sibling instead.

Code for Showing the Presentation in Full Screen and Small Screen

Recall that we also added click event listeners to the full screen and small screen icons. Here's the function responsible for toggling full-screen mode:

Recall that presentationArea refers to the element that wraps the whole presentation. By adding the class full-screen to this element, we trigger the CSS that will expand it to take up the whole screen.

Since we're now in full-screen mode, we need to show the icon for reverting back to the small screen by adding the class .show to it. Finally, we update the variable screenStatus to 1.

For the smallScreenMode function, we do the opposite—we remove the class full-screen , show the expand button icon, and update screenStatus .

Hiding the Left and Right Icons on the First and Last Slides

Now, we need to invent a way to hide the left and right buttons when we're on the first slide and last slide respectively.

We'll use the following two functions to achieve this:

Both these functions perform a very simple task: they check for the current slide number and hide the left and right buttons when the presentation is pointing to the first and last slide respectively.

Updating and Displaying the Slide Number

Because we're making use of the variable currentSlideNo to hide or show the left and right button icons, we need a way to update it as the user navigates through the slides. We also need to display to the user what slide they are currently viewing.

We'll create a function getCurrentSlideNo to update the current slide number:

We start the counter at 0, and for each slide on the page, we increment the counter. We assign the active counter (i.e. with the class .show ) to the currentSlideNo variable.

With that in place, we create another function that inserts some text into the slide counter:

So if we were on the second slide, for example, the slide's counter would read: "2 of 6".

Putting Everything Together

To ensure that all of these functions run in harmony, we'll run them in a newly created init function that we'll execute at the start of the script, just below the references:

We must also run init() at the bottom of both the moveToLeftSlide and moveToRightSlide functions:

This will ensure that the init function runs every time the user navigates left or right in the presentation.

Wrapping Up

I hope this tutorial helped you understand basic web development better. Here we built a presentation slideshow from scratch using HTML, CSS, and JavaScript. It's a great way to get into creating dynamic HTML with JavaScript PPT 

With this project, you should have learned some basic HTML, CSS, and JavaScript syntax to help you with web development.

HTML BASICS Slides Presentation

Click to access all Slides..

This slide presentation shows basics of HTML.

HTML and XHTML are the foundation of all web development. HTML is used as the graphical user interface in client-side programs written in JavaScript. Server-side languages like PHP and Java also receive data from web pages and use HTML as the output mechanism. The emerging Ajax technologies likewise use HTML and XHTML as their visual engine. HTML was once a very loosely-defined language with very little standardization, but as it has become more important, the need for standards has become more apparent. Regardless of whether you choose to write HTML or XHTML, understanding the current standards will help you provide a solid foundation that will simplify all your other web coding. Fortunately HTML and XHTML are actually simpler than they used to be, because much of the functionality has moved to CSS.

Common Elements

Every page (HTML or XHTML shares certain elements in common.) All are essentially plain text files, with the .html extension. HTML files should not be created with a word processor, but in some type of editor that creates plain text. Every page has a large container (HTML or XHTML) and two major subcontainers, the head and the body. The head area contains information useful behind the scenes, such as CSS formatting instructions and JavaScript code. The body contains the part of the page that is visible to the user.

Tags and Attributes

An HTML document is based on the notion of tags. A tag is a piece of text inside angle brackets (<>). Tags typically have a beginning and an end, and usually contain some sort of text inside them. For example, a paragraph is normally denoted like this:

The <p> indicates the beginning of a paragraph. Text is then placed inside the tag, and the end of the paragraph is denoted by an end tag, which is similar to the start tag but with a slash (</p>.) It is common to indent content in a multi-line tag, but it is also legal to place tags on the same line:

Tags are sometimes enhanced by attributes, which are name value pairs that modify the tag. For example, the tag (used to embed an image into a page) usually includes the following attributes:

The src attribute describes where the image file can be found, and the alt attribute describes alternate text that is displayed if the image is unavailable.

Nested tags

Tags can be (and frequently are) nested inside each other. Tags cannot overlap, so <a><b></a></b> is not legal, but <a><b></b></a> is fine.

HTML VS XHTML

HTML has been around for some time. While it has done its job admirably, that job has expanded far more than anybody expected. Early HTML had very limited layout support. Browser manufacturers added many competing standards and web developers came up with clever workarounds, but the result is a lack of standards and frustration for web developers. The latest web standards (XHTML and the emerging HTML 5.0 standard) go back to the original purpose of HTML: to describe the structure of the data only, and leave all formatting to CSS (Please see the DZone CSS Refcard Series). XHTML is nothing more than HTML code conforming to the stricter standards of XML. The same style guidelines are appropriate whether you write in HTML or XHTML (but they tend to be enforced in XHTML):

Most of the requirements of XHTML turn out to be good practice whether you write HTML or XHTML. I recommend using XHTML strict so you can validate your code and know it follows the strictest standards.

XHTML has a number of flavors. The strict type is recommended, as it is the most up-to-date standard which will produce the most predictable results. You can also use a transitional type (which allows deprecated HTML tags) and a frameset type, which allows you to add frames. For most applications, the strict type is preferred.

HTML Template

The following code can be copied and pasted to form the foundation of a basic web page:

The structure of your web pages is critical to the success of programs based on those pages, so use a validating tool to ensure you haven't missed anything

USEFUL OPEN SOURCE TOOLS

Some of the best tools for web development are available through the open source community at no cost at all. Consider these application as part of your HTML toolkit:

PAGE STRUCTURE ELEMENTS

The following elements are part of every web page.

KEY STRUCTURAL ELEMENTS

Most pages contain the following key structural elements:

LISTS AND DATA

Web pages frequently incorporate structured data so HTML includes several useful list and table tag

Standard List Types

HTML supports three primary list types. Ordered lists and unordered lists are the primary list types. By default, ordered lists use numeric identifiers, and unordered lists use bullets.

However, you can use the list-style-type CSS attribute to change the list marker to one of several types.

Lists can be nested inside each other

Definition lists

The special definition list is used for name / value pairs. The definition term (dt) is a word or phrase that is used as the list marker, and the definition data is normally a paragraph:

Use of tables

Tables were used in the past to overcome the page-layout shortcomings of HTML. That use is now deprecated in favor of CSS-based layout. Use tables only as they were intended, to display tabular data.

A table mainly consists of a series of table rows (tr.) Each table row consists of a number of table data (td) elements. The table heading (th) element can be used to indicate a table cell should be marked as a heading.

The rowspan and colspan attributes can be used to make a cell span more than one row or column.

Each row of a table should have the same number of columns, and each column should have the same number of rows. Use of the span attribute may require adjustment to other rows or columns.

LINKS AND IMAGES

Links and images are both used to incorporate external resources into a page. Both are reliant on URIs (Universal Resource Indicators), commonly referred to as URLs or addresses.

<a> (anchor) The anchor tag is used to provide the basic web link:

In this example, http://www.example.com is the site to be visited. The text "link to example.com" will be highlighted as a link.

absolute and relative references

<link>

The link tag is used primarily to pull in external CSS files:

<img>

The img tag is used in to attach an image. Valid formats are .jpg, .png, and .gif. An image should always be accompanied by an alt attribute describing the contents of the image.

Image formatting attributes (height, width, and align) are deprecated in favour of CSS.

SPECIALTY MARKUP

HTML / XHTML includes several specialty tags. These are used to describe special purpose text. They have default styling, but of course the styles can be modified with CSS.

<quote>

The quote tag is intended to display a single line quote:

Quote is an inline tag. If you need a block level quote, use <blockquote>.

<pre>

The <pre> tag is used for pre-formatted text. It is sometimes used for code listings or ASCII art because it preserves carriage returns. Pre-formatted text is usually displayed in a fixed-width font.

<code>

The code format is used to manage pre-formatted text, especially code listings. It is very similar to pre.

<blockquote>

This tag is used to mark multi-line quotes. Frequently it is set off with special fonts and indentation through CSS. It is a block-level tag.

<span>

The span tag is a vanilla inline tag. It has no particular formatting of its own. It is intended to be used with a class or ID when you want to apply style to an inline chunk of code.

The em tag is used for standard emphasis. By default, <em> italicizes text, but you can use CSS to make any other type of emphasis you wish.

<strong>

This tag represents strong emphasis. By default, it is bold, but you can modify the formatting with CSS.

Forms are the standard user input mechanism in HTML / XHTML. You will need another language like JavaScript or PHP to read the contents of the form elements and act upon them.

Form Structure

A number of tags are used to describe the structure of the form. Begin by looking over a basic form:

The <form></form> pair describes the form. In XHTML strict, you must indicate the form's action property. This is typically the server-side program that will read the form. If there is no such program, you can set the action to null ("") The method attribute is used to determine whether the data is sent through the get or post mechanism.

Most form elements are inline tags, and must be encased in a block element. The fieldset is designed exactly for this purpose. Its default appearance draws a box around the form. You can have multiple fieldsets inside a single form.

You can add a legend inside a fieldset. This describes the purpose of the fieldset.

A label is a special inline element that describes a particular field. A label can be paired with an input element by putting that element's ID in the label's for attribute.

The input element is a general purpose inline element. It is meant to be used inside a form, and it is the basis for several types of more specific input. The subtype is indicated by the type attribute. Input elements usually include an id attribute (used for CSS and JavaScript identification) and / or a name attribute (used in server-side programming.) The same element can have both a name and an id.

This element allows a single line of text input:

Passwords display just like textboxes, except rather than showing the text as it is typed, an asterisk appears for each letter. Note that the data is not encoded in any meaningful way. Typing text into a password field is still entirely unsecure.

Radio Button

Radio buttons are used in a group. Only one element of a radio group can be selected at a time. Give all members of a radio group the same name value to indicate they are part of a group.

Attaching a label to a radio button means the user can activate the button by clicking on the corresponding label. For best results, use the selected attribute to force one radio button to be the default.

Checkboxes are much like radio buttons, but they are independent. Like radio buttons, they can be associated with a label.

Hidden fields hold data that is not visible to the user (although it is still visible in the code) It is primarily used to preserve state in server-side programs.

Note that the data is still not protected in any meaningful way.

Buttons are used to signal user input. Buttons can be created through the input tag:

This will create a button with the caption "launch the missiles." When the button is clicked, the page will attempt to run a JavaScript function called "launchMissiles()" Standard buttons are usually used with JavaScript code on the client. The same button can also be created with this alternate format:

This second form is preferred because buttons often require different CSS styles than other input elements. This second form also allows an <img> tag to be placed inside the button, making the image act as the button.

The reset button automatically resets all elements in its form to their default values. It doesn't require any other attributes.

Select / option

Drop-down lists can be created through the select / option mechanism. The select tag creates the overall structure, which is populated by option elements.

The select has an id (for client-side code) or name (for serverside code) identifier. It contains a number of options. Each option has a value which will be returned to the program. The text between <option> and </option> is the value displayed to the user. In some cases (as in this example) the value displayed to the user is not the same as the value used by programs.

Multiple Selections

You can also create a multi-line selection with the select and option tags:

DEPRECATED FORMATTING TAGS

Certain tags common in older forms of HTML are no longer recommended as CSS provides much better alternatives.

The font tag was used to set font color, family (typeface) and size. Numerous CSS attributes replace this capability with much more flexible alternatives. See the CSS refcard for details.

I (italics)

HTML code should indicate the level of emphasis rather than the particular stylistic implications. Italicizing should be done through CSS. The <em> tag represents emphasized text. It produces italic output unless the style is changed to something else. The <i> tag is no longer necessary and is not recommended. Add font-style: italic to the style of any element that should be italicized.

Like italics, boldfacing is considered a style consideration. Use the <strong> tag to denote any text that should be strongly emphasized. By default, this will result in boldfacing the enclosed text. You can add bold emphasis to any style with the font-weight: bold attribute in CSS.

DEPRECATED TECHNIQUES

In addition to the deprecated tags, there are also techniques which were once common in HTML that are no longer recommended.

Frames have been used as a layout mechanism and as a technique for keeping one part of the page static while dynamically loading other parts of the page in separate frames. Use of frames has proven to cause major usability problems. Layout is better handled through CSS techniques, and dynamic page generation is frequently performed through server-side manipulation or AJAX.

Table-based design

Before CSS became widespread, HTML did not have adequate page formatting support. Clever designers used tables to provide an adequate form of page layout. CSS provides a much more flexible and powerful form of layout than tables, and keeps the HTML code largely separated from the styling markup.

HTML ENTITIES

Sometimes you need to display a special character in a web page. HTML has a set of special characters for exactly this purpose. Each of these entities begins with the ampersand(&) followed by a code and a semicolon.

HTML 5 / CSS3 PREVIEW

New technologies are on the horizon. Firefox 3.5 now has support for significant new HTML 5 features, and CSS 3 is not far behind. While the following should still be considered experimental, they are likely to become very important tools in the next few years. Firefox 3.5, Safari 4 (and a few other recent browsers) support the following new features:

Audio and video tags

Finally the browsers have direct support for audio and video without plugin technology. These tags work much like the img tag.

The HTML 5 standard currently supports Ogg Theora video, Ogg Vorbis audio, and wav audio. The Ogg formats are opensource alternatives to proprietary formats, and plenty of free tools convert from more standard video formats to Ogg. The autoplay option causes the element to play automatically. The controls element places controls directly into the page.

The code between the beginning and ending tag will execute if the browser cannot process the audio or video tag. You can place alternate code here for embedding alternate versions (Flash, for example)

The canvas tag offers a region of the page that can be drawn upon (usually with Javascript.) This creates the possibility of real interactive graphics without requiring plugins like Flash.

This is actually a CSS improvement, but it's much needed. It allows you to define a font-face in CSS and include a ttf font file from the server. You can then use this font face in your ordinary CSS and use the downloaded font. If this becomes a standard, we will finally have access to reliable downloadable fonts on the web, which will usher in web typography at long last.

HTML Tags – A to Z List

HTML tags are fundamental elements used to structure and format the content on web pages. It provides the necessary instructions to the web browsers to render text, images, links, and other media content.

What are HTML Tags?

HTML tags are the basic building blocks of any website. They are used to create web pages in various formats. HTML tags are enclosed in angle brackets < > and typically come in pairs, i.e. an opening tag and a closing tag. The closing tag has same text as the opening tag, but has an additional forward-slash ( / ) character. The opening tag specifies the beginning of an element, while the closing tag marks the end. For Example: <p> is an opening tag for a paragraph, and </p> is its corresponding closing tag. Most tags come in pairs, with opening and closing tags, although some tags don’t need to be closed (self-closing tags). Examples of self-closing tags are – <img>, <br>, …, etc. Essential tags f or defining the HTML document structure are  <!DOCTYPE html>, <html>, <head>, and  <body> .

Let’s see a basic example using the HTML tags.

Example:  Basic example demonstrating the HTML tags.

This guide provides an A to Z list of HTML tags , making it a valuable resource for both beginners and experienced web developers.

A to Z HTML Tags

Let us see the extensive list of HTML tags, from A to Z. Whether you are just starting out or need a quick reference, this list has you covered. Each tag in HTML has a specific purpose, for example- defining the document type with  <!DOCTYPE html>  and create hyperlinks with  <a> . Some tags, like  <abbr>  and  <acronym> , provide useful information to browsers, translation systems, and search engines. Others, like  <address> , indicate contact information. This list includes descriptions, syntax, and examples for each tag, helping you understand and utilize them effectively in your web development journey.

HTML Tags – FAQs

How do html tags work.

HTML tags instruct web browsers on how to render content. For example, <p> tags define paragraphs, <a> tags create hyperlinks, and <img> tags embed images. Attributes within tags provide additional information or modify the tag’s behavior.

What are some common HTML tags and their uses?

<h1> to <h6>: Headings of different levels. <p>: Paragraphs of text. <a>: Creates hyperlinks to other web pages or resources. <img>: Embeds images into the web page. <ul>, <ol>, <li>: Creates unordered (bullet) and ordered (numbered) lists.

What are semantic HTML tags?

Semantic HTML tags (<header>, <footer>, <nav>, <main>, <article>, <section>, etc.) provide meaning to the content they enclose, aiding accessibility, SEO (Search Engine Optimization), and structuring of web pages beyond mere presentation.

Which HTML tag is used to define a table?

The <table> tag is used to define tables in HTML. It contains other tags such as <tr> (table row), <th> (table header cell), and <td> (table data cell) to structure tabular data.

What are self-closing HTML tags?

Self-closing tags do not require a closing tag because they don’t contain any content. Examples include <br> for line breaks and <img> for images.

Can HTML tags be nested?

Yes, HTML tags can be nested within each other to create complex structures. For example, you can place a <ul> (unordered list) inside a <div> or <li> (list item) inside an <ol> (ordered list).

How can I learn more about HTML tags?

To learn more about HTML tags, refer to this article individual tags. Additionally, practice creating web pages and experimenting with different tags to understand their behavior and usage better.

This A to Z guide of HTML tags serves as a comprehensive resource, whether you’re a beginner just starting your web development journey or an experienced developer looking for a quick reference. Remember, the power of HTML lies in its simplicity and versatility. By mastering these tags, you can create engaging, accessible, and SEO-friendly websites that not only look good but also function seamlessly.

Web developers starting sometimes need a simple, quick reference list of basic HTML tags. We have an article on the Most used HTML tags- Most commonly used tags in HTML.

HTML is the foundation of webpages, is used for webpage development by structuring websites and web apps.You can learn HTML from the ground up by following this HTML Tutorial and HTML Examples .

How to Create Presentation Slides with HTML and CSS

• March 15, 2022

As I sifted through the various pieces of software that are designed for creating presentation slides, it occurred to me: why learn yet another program, when I can instead use the tools that I’m already familiar with? 

We can easily create beautiful and interactive presentations with HTML, CSS and JavaScript, the three basic web technologies. In this tutorial, we’ll use modern HTML5 markup to structure our slides, we’ll use CSS to style the slides and add some effects, and we’ll use JavaScript to trigger these effects and reorganize the slides based on click events. 

This tutorial is perfect for those of you new to HTML5, CSS and JavaScript, who are looking to learn something new by building.

Here’s the final preview of the presentation slide we’re going to build:

You can also find the complete source code in the GitHub repo .

Let’s begin.

Table of Contents

1. Create the Directory Structure

Before we get started, let’s go ahead and create our folder structure; it should be fairly simple. We’ll need:

index.html css/style.css js/scripts.js

This is a simple base template. Your files remain blank for the time being. We’ll fill that shortly.

2. Create the Starter Markup

Let’s begin by creating the base markup for our presentation page. Paste the following snippet into your index.html file.

<!DOCTYPE html> <html lang=”en”> <head> <meta charset=”UTF-8″> <meta name=”viewport” content=”width=device-width, initial-scale=1.0″> <meta http-equiv=”X-UA-Compatible” content=”ie=edge”> <title>Document</title> <link rel=”stylesheet” href=”css/style.css”>

<!– Font Awesome Icon CDN –> <link rel=”stylesheet” href=”https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0/css/all.min.css” integrity=”sha512-9usAa10IRO0HhonpyAIVpjrylPvoDwiPUiKdWk5t3PyolY1cOd4DSE0Ga+ri4AuTroPR5aQvXU9xC6qOPnzFeg==” crossorigin=”anonymous” referrerpolicy=”no-referrer” /> </head> <body> <div class=”container” <div id=”presentation-area”> <!– slides go here –> </div> </div> <script src=”js/index.js” type=”text/javascript”></script> </body> </html>

From the base markup, you can tell that we are importing Font Awesome Icons, our stylesheet ( style.css ) and our JavaScript ( index.js ). 

Now we’ll add the HTML markup for the actual slides inside the <div> wrapper:

<section class=”presentation”>

<!– Slide 1 –> <div class=”slide show”> <div class=”heading”> Presentation on C# </div> <div class=”content grid center”> <h3 class=”title”> What is C# ? <br /> All You Need To Know </h3> </div> </div>

<!– Slide 1 –> <div class=”slide”> <div class=”heading”> Overview </div> <div class=”content grid center”> <h3 class=”title”> Introduction to C+ </h3> <p class=”sub-title”> Basic and Advanced Concepts </p> <p>Lecture No. 1</p> <p>My Email Address</p> <p><a href=””> [email protected] </a></p> </div> </div>

<!– Add 5 more slides here –> </section>

We have seven slides in total, and each slide is comprised of the heading section and the content section.

Only one slide will be shown at a time. This functionality is handled by the .show class which will be implemented later on in our stylesheet. 

Using JavaScript, later on, we’ll dynamically add the .show class to the active slide on the page.

Below the slides, we’ll add the markup for our slide’s counter and tracker:

<div id=”presentation-area”> <!– <section class=”slides”><-></section> –> <section class=”counter”> 1 of 6 </section> </div>

Later on, we’ll use JavaScript to update the text content as the user navigates through the slides.

Finally, we’ll add the slide navigator just below the counter:

<div id=”presentation-area”> <!– <section class=”slides”><-></section> –> <!– <section class=”counter”><-></section> –> <section class=”navigation”> <button id=”full-screen” class=”btn-screen show”> <i class=”fas fa-expand”></i> </button>

<button id=”small-screen” class=”btn-screen”> <i class=”fas fa-compress”></i> </button>

<button id=”left-btn” class=”btn”> <i class=”fas fa-solid fa-caret-left”></i> </button>

<button id=”right-btn” class=”btn”> <i class=”fa-solid fa-caret-right”></i> </button> </section> </div>

This section consists of four buttons responsible for navigating left and right and switching between full-screen mode and small-screen mode. Again, we’ll use the class .show to regulate which button appears at a time.

That’ll be all for the HTML part, let’s move over to styling.

3. Make It Pretty

Our next step takes place within our stylesheet. We’ll be focusing on both aesthetics as well as functionality here. To make each slide translate from left to right, we’ll need to target the class .show with a stylesheet to show the element.

Here’s the complete stylesheet for our project:

* { margin: 0; padding: 0; box-sizing: border-box; font-family: sans-serif; transition: all 0.5s ease; }

body { width: 100vw; height: 100vh; display: flex; align-items: center; justify-content: center; }

ul { margin-left: 2rem; }

ul li, a { font-size: 1.2em; }

.container { background: #212121; width: 100%; height: 100%; position: relative; display: flex; align-items: center; justify-content: center; }

#presentation-area { width: 1000px; height: 500px; position: relative; background: purple; }

/* Styling all three sections */ #presentation-area .presentation { width: 100%; height: 100%; overflow: hidden; background: #ffffff; position: relative; }

.slide .heading { padding: 2rem; background: purple; font-size: 2em; font-weight: bold; color: #ffffff; }

4. Enable Slide Navigation

Whenever we click on the left or right icon, we want the next slide or previous slide to appear. We also want to be able to toggle between full-screen mode and small-screen mode. 

Furthermore, we want the slide’s counter to display the accurate slide number on every slide. All these features will be enabled with JavaScript.

Inside js/index.js , we’ll begin by storing references to the presentation wrapper, the slides, and the active slide:

let slidesParentDiv = document.querySelector(‘.slides’); let slides = document.querySelectorAll(‘.slide’); let currentSlide = document.querySelector(‘.slide.show’);

Next, we’ll store references to the slide counter and both of the slide navigators (left and right icons):

var slideCounter = document.querySelector(‘.counter’); var leftBtn = document.querySelector(‘#left-btn’); var rightBtn = document.querySelector(‘#right-btn’);

Then store references to the whole presentation container and both button icons for going into full screen and small screen mode:

let presentationArea = document.querySelector(‘#presentation-area’); var fullScreenBtn = document.querySelector(‘#full-screen’); var smallScreenBtn = document.querySelector(‘#small-screen’);

Now that we’re done with the references, we’ll initialize some variables with default values:

var screenStatus = 0; var currentSlideNo = 1 var totalSides = 0;

screenStatus represents the screen orientation. 0 represents a full screen mode and 1 represents a small screen mode. 

currentSlideNo represents the current slide number, which as expected is the first slide. totalSlides is initialized with 0, but this will be replaced by the actual number of our slides.

Moving the Presentation to the Next and Previous Slides

Next, we’ll add click event listeners to the left button, right button, full screen button and small screen button:

leftBtn.addEventListener(‘click’, moveToLeftSlide); rightBtn.addEventListener(‘click’, moveToRightSlide);

fullScreenBtn.addEventListener(‘click’, fullScreenMode); smallScreenBtn.addEventListener(‘click’, smallScreenMode);

We bind corresponding functions that will run when the click event is triggered on the corresponding element.

Here are the two functions responsible for changing the slide:

function moveToLeftSlide() { var tempSlide = currentSlide; currentSlide = currentSlide.previousElementSibling; tempSlide.classList.remove(‘show’); currentSlide.classList.add(‘show’); }

function moveToRightSlide() { var tempSlide = currentSlide; currentSlide = currentSlide.nextElementSibling; tempSlide.classList.remove(‘show’); currentSlide.classList.add(‘show’); }

In the function moveToLeftSlide, we basically access the previous sibling element (ie. the previous slide), remove the .show class on the current slide and add it to that sibling. This will move the presentation to the previous slide.

We do the exact opposite of this in the function moveToRightSlide. Because nextElementSibling is the opposite of previousElementSibling, we’ll be getting the next sibling instead.

Code for Showing the Presentation in Full Screen and Small Screen

Recall that we also added click event listeners to the full screen and small screen icons.

Here’s the function responsible for toggling full-screen mode:

function fullScreenMode() { presentationArea.classList.add(‘full-screen’); fullScreenBtn.classList.remove(‘show’); smallScreenBtn.classList.add(‘show’);

screenStatus = 1; }

function smallScreenMode() { presentationController.classList.remove(‘full-screen’); fullScreenBtn.classList.add(‘show’); smallScreenBtn.classList.remove(‘show’);

screenStatus = 0; }

Recall that presentationArea refers to the element that wraps the whole presentation. By adding the class full-screen to this element, we trigger the CSS that will expand it to take up the whole screen. 

Since we’re now in full-screen mode, we need to show the icon for reverting back to the small screen by adding the class .show to it. Finally, we update the variable screenStatus to 1.

For the smallScreenMode function, the opposite is done – we remove the class full-screen, show the expand button icon, and reupdate screenStatus.

Hidding Left and Right Icons in First and Last Slides 

Now, we need to invent a way to hide both the left and right buttons when we’re on the first slide and last slide respectively.

We’ll use the following two functions to achieve this:

function hideLeftButton() { if(currentSlideNo == 1) { toLeftBtn.classList.remove(‘show’); } else { toLeftBtn.classList.add(‘show’); } }

function hideRightButton() { if(currentSlideNo === totalSides) { toRightBtn.classList.remove(‘show’); } else { toRightBtn.classList.add(‘show’); } }

Both these functions perform a very simple task: they check for the current slide number and hide the left and right buttons when the presentation is pointing to the first and last slide respectively.

Updating and Displaying Slide Number

Because we’re making use of the variable currentSlideNo to hide or show the left and right button icons, we need a way to update it as the user navigates through the slides. 

We also need to display to the user what slide he or she is currently viewing.

We’ll create a function getCurrentSlideNo to update the current slide number:

function getCurrentSlideNo() { let counter = 0;

slides.forEach((slide, i) => { counter++

if(slide.classList.contains(‘show’)){ currentSlideNo = counter; } });

We start the counter at 0, and for each slide on the page, we increment the counter. We assign the active counter (ie. with the class .show) to the currentSlideNo variable. 

With that in place, we create another function that inserts some text into the slide counter:

function setSlideNo() { slideNumber.innerText = `${currentSlideNo} of ${totalSides}` }

So if we were on the second slide for example, the slide’s counter will read as: 2 of 6

Putting Everything Together

To ensure that all of these functions run in harmony, we’ll run them in a newly created init function that we’ll execute at start of the script, just below the references:

function init() {

getCurrentSlideNo(); totalSides = slides.length setSlideNo(); hideLeftButton(); hideRightButton(); }

We must also run init() at the bottom of both the moveToLeftSlide and moveToRightSlide functions:

function moveToLeftSlide() { // other code

function moveToRightSlide() { // other code

This will ensure that the function init runs every time the user navigates left or right in the presentation.

Wrapping Up

I hope this tutorial helped you understand basic web development better. Here we built a presentation slideshow from scratch using HTML, CSS and JavaScript.

With this project, you should have learned some basic HTML, CSS and JavaScript syntax to help you with web development.

How To Build A Captivating Presentation Using HTML, CSS, & JavaScript

Building beautiful presentations is hard. Often you're stuck with Keynote or PowerPoint, and the templates are extremely limited and generic. Well not anymore.

Today, we're going to learn how to create a stunning and animated presentation using HTML, CSS, and JavaScript.

If you're a beginner to web development, don't fret! This tutorial will be easy enough to keep up with. So let's slide right into it!

We're going to be using an awesome framework called Reveal.js . It provides robust functionality for creating interesting and customizable presentations.

• Head over to the Reveal.js repository and clone the project (you can also fork this to your GitHub namespace).

• Change directories into your newly cloned folder and run npm install to download the package dependencies. Then run npm start to run the project.

The index.html file holds all of the markup for the slides. This is one of the downsides of using Reveal.js; all of the content will be placed inside this HTML file.

Built-In Themes

Reveal includes 11 built-in themes for you to choose from:

Changing The Theme

• Open index.html
• Change the CSS import to reflect the theme you want to use

The theme files are:

• solarized.css

Custom Themes

It's quite easy to create a custom theme. Today, I'll be using my custom theme from a presentation I gave called "How To Build Kick-Ass Website: An Introduction To Front-end Development."

Here is what my custom slides look like:

Creating A Custom Theme

• Open css/theme/src inside your IDE. This holds all of the Sass files ( .scss ) for each theme. These files will be transpiled to CSS using Grunt (a JavaScript task runner). If you prefer to write CSS, go ahead and just create the CSS file inside css/theme.
• Create a new  .scss file. I will call mine custom.scss . You may have to stop your localhost and run npm run build to transpile your Sass code to CSS.
• Inside the index.html file, change the CSS theme import in the <head> tag to use the name of the newly created stylesheet. The extension will be  .css , not  .scss .
• Next, I created variables for all of the different styles I wanted to use. You can find custom fonts on Google Fonts. Once the font is downloaded, be sure to add the font URL's into the index.html file.

Here are the variables I chose to use:

• Title Font: Viga
• Content Font: Open Sans
• Code Font: Courier New
• Cursive Font: Great Vibes
• Yellow Color: #F9DC24
• Add a  .reveal class to the custom Sass file. This will wrap all of the styles to ensure our custom theme overrides any defaults. Then, add your custom styling!

Unfortunately, due to time constraints, I'll admit that I used quite a bit of  !important overrides in my CSS. This is horrible practice and I don't recommend it. The reveal.css file has extremely specific CSS styles, so I should have, if I had more time, gone back and ensured my class names were more specific so I could remove the  !importants .

Mixins & Settings

Reveal.js also comes with mixins and settings you can leverage in your custom theme.

To use the mixins and settings, just import the files into your custom theme:

Mixins You can use the vertical-gradient, horizontal-gradient, or radial-gradient mixins to create a neat visual effect.

All you have to do is pass in the required parameters (color value) and voila, you've got a gradient!

Settings In the settings file, you'll find useful variables like heading sizes, default fonts and colors, and more!

The structure for adding new content is:

.reveal > .slides > section

The <section> element represents one slide. Add as many sections as you need for your content.

Vertical Slides

To create vertical slides, simply nest sections.

Transitions

There are several different slide transitions for you to choose from:

To use them, add a data-transition="{name}" to the <section> which contains your slide data.

Fragments are great for highlighting specific pieces of information on your slide. Here is an example.

To use fragments, add a class="fragment {type-of-fragment}" to your element.

The types of fragments can be:

• fade-in-then-out
• fade-in-then-semi-out
• highlight-current-blue
• highlight-red
• highlight-green
• highlight-blue

You can additionally add indices to your elements to indicate in which order they should be highlighted or displayed. You can denote this using the data-fragment-index={index} attribute.

There are way more features to reveal.js which you can leverage to build a beautiful presentation, but these are the main things which got me started.

To learn more about how to format your slides, check out the reveal.js tutorial . All of the code for my presentation can be viewed on GitHub. Feel free to steal my theme!

I really love reveal.js. I haven't spoken in a while so I haven't used it. I've always used their themes and never thought about making my own. This is probably super useful for company presentations, too. I'm SO over google slides. Trying to format code in those is a nightmare LOL

The best thing in this - and now I'm not being ironic - is that while you work on a not so much technical task - creating a presentation - you still have to code. And the result is nice.

On the other hand, I know what my presentation skills teachers would say. Well, because they said it... :) If you really want to deliver a captivating presentation, don't use slides at all. Use the time to prepare what you want to say.

I'm not that good - yet, but taking their advice, if must I use few slides, with little information on them and with minimal graphical distractions. My goal is to impress them by what I say, not is what behind my head.

I'm going to a new training soon, where the first day we have to deliver a presentation supported by slides at a big auditorium and the next day we have to go back and forget about the slides and just get on stage and speak. I can't wait for it.

How about github.com/team-fluxion/slide-gazer ?

It's my fourth attempt at creating a simple presentation tool to help one present ideas quickly without having to spend time within a presentation editor like Microsoft PowerPoint. It directly converts markdown documents into elegant presentations with a few features and is still under development.

Yup, RevealJS is awesome !

Previously I either used PPT or Google Slides. One is a paid license and the other requires an internet connection.

The cool thing about it is that since it's just HTML files behind the scenes, the only software you need to view it with is a web browser. Has amazing syntax-highlighting support via PrismJS. And as a web developer, it makes it simple to integrate other npm packages if need be...

I actually just used it to present a talk this week!

Check out slides.com If you want to skip the heavy lifting and/or use a presentation platform based on reveal.js.

Everything is still easy to customize. The platform provides a UI to work from and an easy way to share your stuff.

BTW - I have no affiliation with slides.com, or even a current account. I used the service a few years back when I regularly presented and wanted to get over PowerPoint, Google Slides, Prezi, etc.

HTML: HyperText Markup Language

HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page's appearance/presentation ( CSS ) or functionality/behavior ( JavaScript ).

"Hypertext" refers to links that connect web pages to one another, either within a single website or between websites. Links are a fundamental aspect of the Web. By uploading content to the Internet and linking it to pages created by other people, you become an active participant in the World Wide Web.

HTML uses "markup" to annotate text, images, and other content for display in a Web browser. HTML markup includes special "elements" such as <head> , <title> , <body> , <header> , <footer> , <article> , <section> , <p> , <div> , <span> , <img> , <aside> , <audio> , <canvas> , <datalist> , <details> , <embed> , <nav> , <search> , <output> , <progress> , <video> , <ul> , <ol> , <li> and many others.

An HTML element is set off from other text in a document by "tags", which consist of the element name surrounded by " < " and " > ". The name of an element inside a tag is case-insensitive. That is, it can be written in uppercase, lowercase, or a mixture. For example, the <title> tag can be written as <Title> , <TITLE> , or in any other way. However, the convention and recommended practice is to write tags in lowercase.

The articles below can help you learn more about HTML.

Key resources

If you're new to web development, be sure to read our HTML Basics article to learn what HTML is and how to use it.

For articles about how to use HTML, as well as tutorials and complete examples, check out our HTML Learning Area .

In our extensive HTML reference section, you'll find the details about every element and attribute in HTML.

Beginner's tutorials

Our HTML Learning Area features multiple modules that teach HTML from the ground up — no previous knowledge required.

This module sets the stage, getting you used to important concepts and syntax such as looking at applying HTML to text, how to create hyperlinks, and how to use HTML to structure a web page.

This module explores how to use HTML to include multimedia in your web pages, including the different ways that images can be included, and how to embed video, audio, and even entire other webpages.

Representing tabular data on a webpage in an understandable, accessible way can be a challenge. This module covers basic table markup, along with more complex features such as implementing captions and summaries.

Forms are a very important part of the Web — these provide much of the functionality you need for interacting with websites, e.g. registering and logging in, sending feedback, buying products, and more. This module gets you started with creating the client-side/front-end parts of forms.

Provides links to sections of content explaining how to use HTML to solve very common problems when creating a web page: dealing with titles, adding images or videos, emphasizing content, creating a basic form, etc.

Advanced topics

The crossorigin attribute, in combination with an appropriate CORS header, allows images defined by the <img> element to be loaded from foreign origins and used in a <canvas> element as if they were being loaded from the current origin.

Some HTML elements that provide support for CORS , such as <img> or <video> , have a crossorigin attribute ( crossOrigin property), which lets you configure the CORS requests for the element's fetched data.

The preload value of the <link> element's rel attribute allows you to write declarative fetch requests in your HTML <head> , specifying resources that your pages will need very soon after loading, which you therefore want to start preloading early in the lifecycle of a page load, before the browser's main rendering machinery kicks in. This ensures that they are made available earlier and are less likely to block the page's first render, leading to performance improvements. This article provides a basic guide to how preload works.

HTML consists of elements , each of which may be modified by some number of attributes . HTML documents are connected to each other with links .

Browse a list of all HTML elements .

Elements in HTML have attributes . These are additional values that configure the elements or adjust their behavior in various ways.

Global attributes may be specified on all HTML elements , even those not specified in the standard . This means that any non-standard elements must still permit these attributes, even though those elements make the document HTML5-noncompliant.

HTML elements are usually "inline-level" or "block-level" elements. An inline-level element occupies only the space bounded by the tags that define it. A block-level element occupies the entire space of its parent element (container), thereby creating a "block box".

HTML comments are used to add explanatory notes to the markup or to prevent the browser from interpreting specific parts of the document.

The <audio> and <video> elements allow you to play audio and video media natively within your content without the need for external software support.

HTML is comprised of several kinds of content, each of which is allowed to be used in certain contexts and is disallowed in others. Similarly, each context has a set of other content categories it can contain and elements that can or can't be used in them. This is a guide to these categories.

HTML Structure and Presentation

Web pages are typically created using three components, HTML , CSS and JavaScript.

There is a special relationship between HTML and CSS.  HTML can exist without CSS, but CSS is pointless without any HTML to style.

Hypertext Markup Language (HTML)

HTML is markup language used to create web pages.

HTML pages are interpreted by a web browser .

HTML tags are added to each element of content in order to provide meaning and context.

Further HTML tags can be used to divide a page into logical sections (divisions), making different layouts possible when combined with CSS.

Images, tables and hyperlinks are also included using HTML.

Although it is entirely possible to make a website just using HTML, it would look bland and unappealing.

To create web pages that are visually stunning and easy to use, we need to use another language called CSS.

Example of HTML

<p> This is a very short paragraph. </p>

Cascading Style Sheets (CSS)

CSS is a presentation language.  Its purpose is to provide a web browser with styling instructions for the HTML.

CSS can be included directly in the HTML tags, in the head section of the HTML, or in an entirely separate document (CSS style sheet).

CSS is a very powerful tool, enabling very complex and unique designs to be made possible.

Take a look at the CSS Zen Garden website to see how changing CSS can make a dramatic difference to the appearance of HTML.

Example of CSS

p { color: blue }

A-Level Designing Web pages using HTML and CSS (16-18 years)

Html structure.

HTML (Hypertext Markup Language) is the recognised markup language utilised in forming web pages.  It defines the composition of web pages by using markup.  HTML elements are the primary units of HTML pages and are denoted by tags.  HTML tags label parts of content like headings, paragraphs, and tables.  Browsers do not show the HTML tags, but they are used in the background in order to deliver the content of the page.

HTML tags are element names enclosed by angle brackets.  HTML tags usually come in pairs.  The first tag in a pair is the start tag, and the second tag is the end tag.  The end tag is written like the start tag, but with a forward slash inserted before the tag name.  The start tag is sometimes also called the opening tag, and the end tags are the closing tag.

All HTML documents must start with a document type declaration: <!DOCTYPE html>.  The HTML document itself begins with <html> and ends with </html>.  The visible part of the HTML document is between <body> and </body>.

HTML tags are not case sensitive.

HTML Attributes

All HTML elements can have attributes, which provide additional information about the element, and are always specified in the start tag.  They usually come in name/value pairs.

CSS (Cascading Style Sheets) defines how HTML elements are to be presented on any given screen, paper or other media.  It saves the developer a lot of work since it can control the layout of multiple web pages simultaneously.

Ways to add CSS to HTML Elements

• Inline – used to apply a unique style to a single HTML element. It uses the style attribute of an HTML element.
• Internal – used to describe a style for one HTML page. It is indicated in the <head> section of an HTML page, within a <style> element.
• External – used to define the style for multiple HTML pages by using an external CSS file. You can change the look of an entire website by changing one file.  This is the most common way to add CSS to HTML elements.

HTML Structure vs. HTML Presentation

The composition of a webpage could be regarded as a mixture of the following four elements:

• Content is the general term used for all the browser-displayed information elements—such as text, audio, still images, animation, video, multimedia, and files belonging to web pages. It does not require any additional presentational markups or styles in order to fully relay its message.
• Structure is the name given to the practice of using HTML in content to transmit substance, and also to define how blocks of information are structured in relation to one another. Examples include: “This is a list,” (i, d, k), “This is heading and subheading,” (<h1>, <h2>, …, <h6>), “This section is related to,” (<a>), etc.
• Presentation of Style refers to anything related to how the content and structure is presented. Examples include size, color, margins, borders, layout, location, etc.
• Behaviour or Interactivity is the implementation of client-side script to generate a two-way flow of information between the webpage and its users. JavaScript is an example of this.

Most of the time it is difficult to clearly distinguish content from the structure.  For example, the <img> tag, as a structural element, is used to produce graphical content.  In practice, the composition of a webpage can simply be viewed as a mixture of three elements: Structure, Presentation and Behavior.

The following terms are often used in correspondence with one another: separation of content and presentation, separation of meaning and presentation, and separation of structure and presentation.  Nonetheless, all of these terms basically make reference to the separation of the content (which is made meaningful by structure and presentation), or simply acknowledge the separation of the structure (HTML) and the presentation (CSS) of any given webpage.

The main goal of HTML 4.01 is the separation of structure and presentation,  as specified in section 2.4.1 of HTML 4.01.

An Introduction to HTML for Beginners

HTML, which stands for HyperText Markup Language, serves as the foundation of web development. It enables you to create interactive web pages, structure content, and effectively communicate your message.

In this guide, we'll explore HTML comprehensively, addressing essential questions to provide a strong foundation for budding web developers.

The Crucial Role of HTML in Web Development

HTML plays an essential role in web development as it defines the structure and content of web pages. It serves as the backbone upon which websites are built.

HTML accomplishes this by utilizing a system of tags and elements, each serving a unique purpose.

How Do I Write HTML Code?

Writing HTML code is a matter of understanding HTML tags.

Tags are enclosed within angle brackets, each comprising an opening and closing part. They function as building blocks that define the structure of your web page.

Think of them as the bricks and mortar of web development. Understanding their roles is essential for web development.

How to Create a Website Using HTML?

Creating a website using HTML involves several key steps. Let's go over them in the following sections.

Website Planning

Before you start coding, take time to plan your website thoroughly.

Identify your target audience, outline the content and structure of your site and design a layout that aligns with your goals.

Keep in mind that the visual design can be enhanced with CSS (Cascading Style Sheets), a topic we'll explore later in your web development journey.

Writing HTML Code

Open a text editor, such as Visual Studio Code or Sublime Text, and begin writing HTML code.

Start with the basic structure, including <!DOCTYPE html> , <html> </html> , <head> </head> , and <body> </body> .

Then, populate the body with your content.

Saving as .html

Save your HTML files with a .html extension to indicate that they are web pages. Proper file naming is essential for organizing your project.

Local Testing

To see how your website looks and functions, open your HTML files in a web browser. This local testing phase allows you to fine-tune your design and layout.

Hosting and Publishing

For your website to be accessible on the internet, you'll need web hosting services. Various providers offer hosting, and you'll typically obtain a domain name (for example, www.yourwebsite.com) to point to your hosted site.

How to Start HTML Code?

Starting HTML code is straightforward. Let's go over each step in the following sections.

Text Editor Selection

Choose a text editor that suits your needs. Popular options include Visual Studio Code, Sublime Text, and Atom. These editors offer features like syntax highlighting and autocompletion tailored to web development.

HTML5 Declaration

Initiate your HTML document with <!DOCTYPE html> . This declaration signifies the use of HTML5, the latest HTML standard.

Building the Structure

Inside the <html> </html> tags, create your HTML structure.

The <head> </head> section contains metadata, including the page title, and the <body> </body> section houses the visible content of your web page.

Adding Metadata

Within the <head> </head> section, utilize the <meta> tag to specify the character encoding, ensuring proper rendering.

How Do I Run HTML Code Step by Step?

Executing HTML code is straightforward, thanks to modern web browsers. Here's a step-by-step guide:

Save Your HTML File

Ensure that your HTML file is saved with a .html extension. This signals to your computer that it's an HTML document.

Double-Click to Open

Double-click the HTML file, and your default web browser will automatically open it. Your browser renders the HTML, displaying your web page.

Alternative Browsers

If you prefer a specific web browser, you can right-click the HTML file and choose "Open with" to select your preferred browser.

Inspect and Debug

Modern web browsers come equipped with built-in developer tools that enable you to inspect and debug your HTML, CSS, and JavaScript.

Access these tools by right-clicking on your web page and selecting "Inspect" or by pressing F12 or Ctrl+Shift+I (Windows) or Cmd+Option+I (Mac).

How Do You Write "Hello" in HTML?

Displaying "Hello" on a web page is straightforward. You can use the <h1> tag to create a top-level heading, as demonstrated earlier.

HTML offers multiple ways to present "Hello." For instance:

Or you can use a paragraph tag:

Both options result in "Hello!" being displayed on your web page. The choice depends on the context and your styling preferences.

It's worth noting that HTML has six levels of headings, ranging from <h1> (the highest) to <h6> (the lowest). Headings are used to structure content hierarchically, with <h1> representing the main heading and <h6> representing subheadings.

How to Create an HTML File with an Example?

Creating an HTML file is your gateway to web development. Here's an expanded step-by-step guide:

Choose a Text Editor

Select a text editor that suits your workflow and preferences. Modern editors offer features like syntax highlighting and autocompletion, enhancing your coding experience.

Structure Your HTML

Begin your HTML document with <!DOCTYPE html> , followed by <html> </html> tags to enclose your content. Inside the <head> </head> section, set metadata, such as the page title and character encoding, using the <meta> tag.

Add Content

Within the <body> </body> section, insert your content. Experiment with various HTML tags to format your content, including headings, paragraphs, lists, links, and images.

Save with .html Extension

Save your file with a .html extension. This naming convention ensures that your computer recognizes it as an HTML document.

Preview Locally

Double-click the HTML file to open it in your web browser. This provides an instant preview of your webpage, allowing you to see how it appears to your audience.

Introducing CSS for Styling

While HTML defines the structure of your web page, CSS (Cascading Style Sheets) is used for styling. You can link an external CSS file to your HTML to control the design and layout of your webpage. For example:

This separation of content (HTML) and presentation (CSS) is a fundamental practice in web development.

How Do You Write a Sentence in HTML?

To create a sentence in HTML, you can employ the <p> (paragraph) tag, as mentioned earlier. However, HTML offers flexibility, allowing you to use other inline tags for shorter text snippets. Here's an example:

Alternatively, for shorter text, you can use the <span> tag:

The <p> tag is typically used for paragraphs, while the <span> tag is more versatile and is often used for inline elements within a sentence or paragraph. Choose the tag that suits the context of your content.

Additional HTML Elements to Explore

While we've covered the basics, HTML offers a plethora of elements and attributes for creating rich and interactive web experiences. Here are some additional HTML elements you can explore:

HTML provides elements like <form> , <input> and <button> to create user-friendly forms for collecting data.

You can use <table> , <tr> , <td> and other related tags to structure tabular data.

Embed images, audio, and video using <img> , <audio> , and <video> tags.

Links and Anchors

Create hyperlinks using the <a> tag to connect web pages and external resources.

Use <ul> for unordered lists, <ol> for ordered lists and <li> for list items.

Semantic Tags

HTML5 introduced semantic elements like <header> , <nav> , <section> , <article> and <footer> to enhance the structure and accessibility of web pages.

Further refine your document with meta tags, including those for specifying character encoding, viewport settings, and author information.

In closing, HTML is your gateway to web development. It provides the foundation upon which you can build stunning web experiences and effectively communicate with your audience.

Whether you're embarking on creating a personal blog, launching an e-commerce site, or showcasing your portfolio, HTML forms the foundation of your online presence.

As you progress in web development, remember that HTML is just the beginning of your journey. Complement your HTML skills with CSS for styling and JavaScript for interactivity. This approach empowers you to create dynamic and engaging websites that captivate the attention of your audience.

In your pursuit of web development excellence, embrace the challenges and endless possibilities presented by HTML and the ever-evolving field of web technologies. Stay curious, never stop learning, and remain current with the latest standards and best practices. Connect with me on Twitter .

HTML Tags: Presentational vs Structural

I found many different views on many articles on presentation tags, with some people thinking all tags are presentational , but some others do not think so.

For example: in the HTML 5 specification, they do not think <small> is presentational.

In this list of tags - which are all HTML 5 supported - which tag is presentational and which is not?

Who decides which HTML tag is presentational and Which is not - and how do they make that decision? Is it a particularly large group such as the W3C or is it based on groups of web developers, i.e. the web community? Also, between the two, which advice we should follow for deciding which tags are presentational?

If a tag is valid as according to the W3C in accepted doctypes, then what are the pros to not using any xhtml tag from any point of view?

in user/usability/accessibility point of view

if we use more HTML tags then pages without CSS will better.

in developer point of view

if we make use of more available tags in HTML, than we do not need to use <span class=className">

it takes more time to write and it uses more charter space than tags in HTML and CSS both.

For example:

instead of using:

We can use:

it looks cleaner, it is easier to use , it uses less characters - which will reduce the page size - and it is more readable in source. It also does not break the rule of content and presentation separation.

We can also do this:

and whenever we want to change font-weight then we can change css only in both examples.

If a tag is considered valid by w3c in their recognized doctypes, then what are the pros to not using any X/HTML presentational tags which are not directly recognized by either the W3C, or by the HTML specifications?

Can we change any design parameters without changing anything in HTML? Does this fit within the meme of content and presentation separation?

If any HTML tag breaks the rule of separation, then does not the css property Content break as well?

see this article .

Why are the HEIGHT and WIDTH attributes for the IMG element permitted?. does it not break the rule of separation? A good debate on this matter can be found here .

W3C decides the semantics of tags. The specification documents of HTML5 gives conditions on the use of the various tags.

To continue with your example, there is nothing wrong with using <b> to bold some text unless:

The text being bolded is a single entity already represented by a tag:

Incorrect: <label for="name"><b>Name:</b></label> Correct: (Use CSS to style the element) label { font-weight: bold; } <label for="name">Name:</label>

The text is being bolded to put added emphasis and weight on a section or words of a block of text.

Incorrect: <p>HTML has been created to <b>semantically</b> represent documents.</p> Correct: (Use <strong> ) <p>HTML has been created to <strong>semantically</strong> represent documents.</p>

The following is an example of proper use of the <b> tag:

Correct: <p>You may <b>logout</b> at any time.</p>

I realize that there doesn't seem to be a lot of difference between the above example and the one using <strong> as the proper example. To simply explain it, the word semantically plays an important role in the sentence and its emphasis is being strengthened by bold font, while logout is simply bolded for presentation purposes.

The following would be an improper usage.

Incorrect: <p><b>Warning:</b> Following the procedure described below may irreparably damage your equipment.</p> Correct: (This is used to add strong emphasis, therefore use <strong> ) <p><strong>Warning:</strong> Following the procedure described below may irreparably damage your equipment.</p>

Using <span class="bold"> is markup-smell and simply shouldn't be allowed. The <span> element is used to apply style on inline elements when a generic presentation tag (ie.: <b> doesn't apply) For example to make some text green:

Incorrect: <p>You will also be happy to know <span class="bold">ACME Corp</span> is a <span class="eco-green">certified green</span> company.</p> Correct: (Explanation below) <p>You will also be happy to know <b>ACME Corp</b> is a <em class="eco-green">certified green</em> company.</p>

The reason here why you would want to use <em> as opposed to <span> for the word green is because the color green here is used to add emphasis on the fact that ACME Corp is a certified green company.

The following would be a good example of the use of a <span> tag:

Correct: <p>You may press <kbd>CTRL+G</hbd> at any time to change your pen color to <span class="pen-green">green</span>.</p>

In this example, the word green is styled in green simply to reflect the color, not to add any emphasis ( <em> ) or strong emphasis ( <strong> ).

• Even using <b> for "(required)" or "ACME Corp" is wrong. It should be something like <span class="required"> and <span class="company"> respectively, which describes what those strings are; they're not "a bold", whatever that is. :-) –  C. K. Young Commented Feb 14, 2010 at 5:58
• As for "ducks", that's what <dfn> is for. :-) Style it with bold if you prefer, but seriously, I wouldn't use wiki markup as the model of "right markup". –  C. K. Young Commented Feb 14, 2010 at 6:01
• @Chris Jester-Young: <span> IS NEVER semantic. It is a generic element used when the element represented doesn't fit any other category. While I agree that <span class="required"> would be the proper way to go here, I have to disagree for the company, as it is used once. In the case of a company listing or a particular page where the company has a certain meaning, then <span class="company"> would be the way to go. You are also right about <dfn> , I forgot about that element. Finding another example... –  Andrew Moore Commented Feb 14, 2010 at 6:04
• @Andrew: <span> itself is not semantic. It's the classes you attach to it that's semantic. The point of <span> and <div> is that they're (supposed to be) free of overloaded presentational assumptions. –  C. K. Young Commented Feb 14, 2010 at 6:07
• @Chris Jester-Young: correct, but the classes attached to them need to have a meaning related to the data enclosed in them. By using <span class="company"> , you are implying that the company has an importance in the data structure of the document, while in this case it is simply part of the text and not a meaningful entity. –  Andrew Moore Commented Feb 14, 2010 at 6:09

The whole distinction between "presentation" elements versus "structure" element is, in my opinion, a matter of common sense, not something defined by W3C or anyone else. :-P

An element that describes what its content is (as opposed to how it should look) is a structure element. Everything else is, by definition, not structural, and therefore a presentation element.

Now, I'll answer the second part of your post. I understand this is a contentious topic, but I'll speak my mind anyway.

Well-made HTML should not concern itself with how it should look. That's the job of the stylesheet. The reason it should leave it to the stylesheet, is so you can deliver one stylesheet for desktop computers, another one for netbooks, smartphones, "dumbphones" (for lack of a better term), Kindles, and (if you care about accessibility, and you should) screen readers.

By using presentation markup in your HTML, you force a certain "look" across all these different types of media, removing the ability of the designer to choose a look that works best for such devices. This is micromanagement of the worst sort, and designers will hate you for it. :-)

To use your example, instead of using <b> , you should ask yourself what the boldness is supposed to express. If you're trying to express a section title, use one of the header tags ( <h1> through <h6> ). If you're trying to express strong emphasis, use <strong> . You get the idea. Express the what , not the how ; leave the how to the stylesheet designers.

</soapbox>

• 1 To me, <small> is not semantic (I disagree with the "accepted answer"; fine print can have its own class, and it's not called "small"), but, I understand that reasonable people disagree about this. I would still avoid using <small> . To your first point, I agree that <b> is less evil than <span class="boldText"> . But to whatever extent the class can be amended to specify a "what", even better. –  C. K. Young Commented Feb 14, 2010 at 6:05
• 1 @Jitendra: <br /> is semantic if the data represented by the parent entity contains a line-break and <br /> is used to represent it. <hr /> is semantic if the data represented by the parent entity contains a section break or a page break and <hr /> is used to represent it (this is debatable). If used purely for display purposes, the tag has no semantic value. I would still classify <hr /> as presentational, but not <br /> –  Andrew Moore Commented Feb 14, 2010 at 6:37
• 1 @Jitendra: I think both <br> and <hr> have a place in structural markup. (Line breaks are used for flowing poetry a certain way, for example. Think of how one lays out a haiku.) I try to use them very sparingly, though. –  C. K. Young Commented Feb 14, 2010 at 6:45
• 1 @Jitendra: When looking at document semantics, always look if the data represented by the entity/attribute has a meaning to the data structure of the document or not. Using content: to add quotes around text located in a <q> element doesn't affect data structure (it is a quote after all the " are purely display elements, the quote itself is the data). Using the width and height attributes CAN affect data structure when the width/height of an image has meaning in the data structure. Therefore, it is semantic to use the attributes when it is meaningful to the document... –  Andrew Moore Commented Feb 14, 2010 at 6:48
• 1 ... the border attribute for example never adds to the data meaning of a document. Same applies to the fgcolor and bgcolor attribute of the <body> element. If width and height attribute has no intrinsic value to the data meaning of the element and is used purely for presentation purposes, you should style it using CSS. –  Andrew Moore Commented Feb 14, 2010 at 6:50

It's not that presentational elements should be avoided, it's that markup should be as semantic as possible. When designing a document structure, default styling should be considered a secondary affect. If an element is used solely for presentation, it's not semantic, no matter what element is used.

The example usage of <b> isn't semantic, because <b> imparts no meaning. <span class="boldtext"> also isn't semantic. As such, their usage is mixing presentation into the structure.

The ability to incorporate multimedia elements and interactive features makes HTML5 presentations a powerful tool for conveying complex information in an engaging and understandable way.

How can I make my HTML5 presentation accessible to all users?

To make your HTML5 presentation accessible, ensure that all content is readable and navigable for users with different abilities. This includes providing alternative text for images, captions for videos, and using clear and simple language. Additionally, make sure your presentation is responsive, meaning it adjusts to fit different screen sizes and orientations.

HTML PPT: Meaning, Versions, Tags, Pros, Cons

HTML, or Hypertext Markup Language, is the standard language used to create web pages. It structures content on the web by defining elements like headings, paragraphs, links, images, and more. HTML uses tags, written in angle brackets, to tell a browser how to display content. For example, the <p> tag is used for paragraphs, while the <a> tag creates hyperlinks.

It’s a foundational language for web development and works alongside CSS (for styling) and JavaScript (for interactivity). While basic HTML is simple to learn, mastering it allows for building and organizing complex websites and online applications.
