What is HTML, and why is it important?

HTML (HyperText Markup Language) is the standard language for creating web pages. It uses tags to structure content, making it readable and organized for browsers to display. It is essential because it forms the foundation of all websites.

Example:

<!DOCTYPE html>
<html>
<head>
  <title>Sample Page</title>
</head>
<body>
  <h1>Hello, World!</h1>
</body>
</html>
