1. What is HTML?

HTML (HyperText Markup Language) is the standard language used to create and structure content on the web. It uses tags to define elements like headings, paragraphs, and links.

<html>
<head>
  <title>My First Web Page</title>
</head>
<body>
  <h1>Welcome to My Website</h1>
  <p>This is a paragraph of text.</p>
</body>
</html>

  • XHTML: Stricter version of HTML. Follows XML rules (e.g., requires well-formed documents).

Example of XHTML:


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title>XHTML Example</title>
</head>
<body>
  <p>This is a well-formed XHTML document.</p>
</body>
</html>
