What is HTML?
HTML (HyperText Markup Language) is the backbone of every website you visit. Think of it as the skeleton that gives structure to web pages - it tells the browser what content to display and how to organize it. HTML uses simple text-based codes called 'tags' to mark up different parts of your content, like headings, paragraphs, images, and links.
Understanding HTML: The House Analogy
Imagine building a house. HTML is like the blueprint and framework - it defines where the rooms go, where the doors and windows are placed, and the basic structure. CSS would be the paint, decorations, and furniture (how it looks), while JavaScript would be the electricity and plumbing (how it works).
html
1<!-- HTML: The Structure -->
2<div class="house">
3 <header class="roof">🏠 My Website</header>
4 <nav class="hallway">
5 <a href="#home">Home</a>
6 <a href="#about">About</a>
7 </nav>
8 <main class="living-room">
9 <h1>Welcome to my home page!</h1>
10 <p>This is where the main content lives.</p>
11 </main>
12 <footer class="basement">© 2024 My Website</footer>
13</div>Visual Example: From Code to Webpage
Here's a simple example showing how HTML code transforms into what you see in a browser:
html
1<!DOCTYPE html>
2<html>
3<head>
4 <title>My First Webpage</title>
5</head>
6<body>
7 <h1>🌟 Welcome to My Blog</h1>

<h1>- Creates a large main heading with emoji<h2>- Creates a smaller subheading<strong>- Makes text bold and emphasizes importance<ul> and <li>- Creates a bulleted list with items<a href="...">- Creates a clickable link to another website<img>- Displays an image with alternative text
Interactive Elements Example

html
1<form>
2 <h3>📝 Contact Form</h3>
3 <label for="name">Your Name:</label>
4 <input type="text" id="name" placeholder="Enter your name">
