W3C XHTML 1999

XHTML (Extensible Hypertext Markup Language) is a markup language that is an extension of HTML. It was developed by the World Wide Web Consortium (W3C) to create a more structured and cleaner version of HTML. XHTML follows the rules of XML, which makes it easier for web developers to write a code that is both human and machine-readable.

Benefits of XHTML
  1. Consistency: XHTML is a standardized markup language which ensures consistency in web development. This consistency helps in creating a website that is easy to maintain and update.
  2. Cross-Browser Compatibility: XHTML code is designed to work across different browsers, which helps in ensuring that your website is accessible to a wider audience.
  3. Search Engine Optimization: XHTML code is clean and structured, which makes it easier for search engines to crawl and index your website. This can help in improving your website's visibility on search engines.
  4. Separation of content and presentation: XHTML code separates the content and presentation of the website, which helps in maintaining consistency and makes it easier to update the website's design.

	<head>
		<title>My XHTML Page</title>
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
	</head>
	<body>
		<h1>Welcome to my XHTML page</h1>
		<p>This is a paragraph of text.</p>
