In modern web design, creating a clear and meaningful page structure is essential. Semantic layout tags in HTML help you define different parts of a webpage with meaningful names.
They make your code easier to read, maintain, and improve accessibility for both users and search engines.
Before HTML5, developers commonly used <div> elements everywhere, giving them IDs or classes like header, footer, or content.
Now, HTML5 introduces semantic elements that describe their purpose directly — no extra naming required!
Common Semantic Layout Tags
| Tag | Description |
|---|---|
<header> | Represents the top section of a webpage or a section — often contains a logo, navigation, or introductory content. |
<nav> | Defines navigation links to other pages or sections. |
<main> | Represents the main content area unique to the page. |
<section> | Groups related content into a logical block, usually with a heading. |
<article> | Represents a self-contained piece of content that could stand alone (like a blog post or news article). |
<aside> | Defines content indirectly related to the main content, such as sidebars or ads. |
<footer> | Represents the bottom section of a page or section, usually containing copyright or contact info. |
<figure> & <figcaption> | Used to include images or diagrams with captions. |
Example: Basic Semantic Layout
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
