Design a Semantic HTML Layout Using <header>, <nav>, <main>, and <footer>
Creating a structured and clean layout in HTML is important for accessibility, SEO, and easier maintenance. In this tutorial, you’ll learn how to use semantic HTML tags like <header>, <nav>, <main>, and <footer> to build a basic web page layout.
🌟 What is Semantic HTML?
Semantic HTML means using HTML tags that describe the purpose of the content inside them. These tags help both browsers and developers understand the structure of the page.
For example:
-
<header>– for the top section of the page. -
<nav>– for navigation menus. -
<main>– for the main content. -
<footer>– for the bottom/footer part.
Using semantic HTML improves:
-
Accessibility (screen readers can navigate better)
-
SEO (search engines understand your content)
-
Code readability
💡 Basic Structure Using Semantic Tags
Here’s a complete HTML example using semantic elements:
<!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="Learn how to design a semantic HTML layout using header, nav, main, and footer.">
<title>My Semantic HTML Layout</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
}
header, nav, main, footer {
padding: 20px;
}
header {
background-color: #4CAF50;
color: white;
}
nav {
background-color: #f2f2f2;
}
main {
background-color: #fff;
min-height: 300px;
}
footer {
background-color: #333;
color: white;
text-align: center;
}
</style>
</head>
<body>
<header>
<h1>My Website</h1>
<p>Welcome to my site built with semantic HTML5!</p>
</header>
<nav>
<ul style="list-style: none; padding: 0;">
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Contact</a></li>
</ul>
</nav>
<main>
<h2>Main Content Area</h2>
<p>This is where the main content of your web page will go. It is wrapped in a `<main>` tag which tells browsers that this is the primary content of the page.</p>
</main>
<footer>
<p>© 2025 My Website. All rights reserved.</p>
</footer>
</body>
</html>
