<html>
<head>
<title>My First HTML Page</title>
</head>
<body>
<h1>Welcome to My Website!</h1>
<p>This is a paragraph of text.</p>
</body>
</html>Explanation:
<!DOCTYPE html>: Declares the document as HTML5.<html>: The root element containing all the content.<head>: Contains meta-information like the title and links to CSS or JavaScript files.<body>: Includes the visible content of the web page.
