HTML5 provides the foundational scaffolding structural environment for web documents. It categorizes contents using structural elements so browsers understand how data records are ordered on a digital display viewport.
Semantic tags cleanly convey raw operational meaning directly to both target user browsers and search engine optimization crawler bots:
<header> - Navigation menus and structural intros <nav> - Hyperlink maps and navigation nodes <main> - Central targeted document structural core <article> - Self-contained structural blocks <footer> - Disclaimer documentation and info blocks
<!DOCTYPE html>
<html lang="en">
<head>
<title>Page Title</title>
</head>
<body>
<h1>Welcome Header</h1>
<p>Paragraph body content.</p>
</body>
</html>
