What is HTML5?

HTML5 is the latest version of HyperText Markup Language, the standard markup language for creating web pages. It introduces new semantic elements, improved accessibility, and better support for multimedia content.

Basic HTML5 Document Structure

Every HTML5 document follows this basic structure:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="description" content="Your page description">
    <title>Your Page Title</title>
</head>
<body>
    <!-- Your content goes here -->
</body>
</html>

Key Components Explained:

  • <!DOCTYPE html> - Declares this as an HTML5 document
  • <html lang="en"> - Root element with language attribute
  • <head> - Contains metadata and links to external resources
  • <meta charset="UTF-8"> - Specifies character encoding
  • <meta name="viewport"> - Makes page responsive on mobile devices
  • <title> - Sets the browser tab title
  • <body> - Contains all visible page content
