1. Introduction

What is HTML?

HTML (HyperText Markup Language) is the standard markup language used to create and structure web pages. It helps browsers display content such as text, images, links, tables, forms, audio, and video.

HTML is not a programming language. It is a markup language that defines the structure of web content. HTML works together with CSS for styling and JavaScript for interactivity.

Why HTML is Important

HTML is the foundation of every website and web application. It helps developers organize content properly and allows browsers to display webpages correctly.

Modern HTML also supports multimedia, semantic elements, accessibility, and responsive web design.

Uses of HTML

HTML is used for:

Creating websites
Building forms
Embedding multimedia
Creating tables and lists
Designing web interfaces
Linking webpages

2. History of HTML

HTML was created by Tim Berners-Lee in 1991 while working at CERN. The first version of HTML contained simple tags for headings, paragraphs, and links.

Over time, HTML evolved from HTML 1.0 to HTML5 with support for multimedia, semantic elements, APIs, and responsive design.

Evolution of HTML

HTML 1.0

<p>Basic HTML page.</p>

  <input type="text" placeholder="Enter Name">
</form>

HTML 3.2

<table border="1">
  <tr>
    <td>HTML</td>
    <td>CSS</td>
  </tr>
</table>

HTML 4.01

<div>
  <h2>Welcome</h2>
</div>

XHTML

<img src="image.jpg" alt="Image" />

HTML5

3. Features of HTML

Easy to Learn

HTML uses simple tags and beginner-friendly syntax.

<h1>Hello</h1>
<p>This is HTML.</p>

Platform Independent

HTML works on all operating systems and browsers such as Chrome, Firefox, Edge, and Safari.

Semantic Structure

HTML5 introduced semantic tags that improve readability, SEO, and accessibility.

<header>
  <h1>My Website</h1>
</header>

<section>
  <p>Welcome</p>
</section>

<footer>
  <p>Footer</p>
</footer>

Works with CSS and JavaScript

HTML provides structure, CSS handles styling, and JavaScript adds functionality.

<!DOCTYPE html>
<html>
<head>
  <style>
    h1 {
      color: blue;
    }
  </style>
</head>

<body>

  <h1 id="title">Hello</h1>

  <script>
    document.getElementById("title").innerHTML = "Welcome";
  </script>

</body>
</html>

4. Structure of an HTML Document

A basic HTML document contains the following structure:

<!DOCTYPE html>
<html>
<head>
  <title>My Webpage</title>
</head>

<body>

  <p>This is a webpage.</p>

</body>
