What is HTML?
HTML (HyperText Markup Language) is the standard markup language for web pages. It defines the structure and content of a page using elements (tags). Every website you visit is built on HTML.
Basic Structure
<!DOCTYPE html>
<html lang="en">
<head>
<title>My Page</title>
</head>
<body>
<h1>Hello World</h1>
<p>This is a paragraph.</p>
</body>
</html>Common Elements
| Tag | Purpose |
|---|---|
| <h1>–<h6> | Headings |
| <p> | Paragraph |
| <a> | Link |
| <img> | Image |
| <ul> / <ol> | Lists |
How Browsers Use HTML
The browser parses HTML into a DOM (Document Object Model) tree, applies CSS for styling, then runs JavaScript for interactivity.
