The <main></main> element in an HTML document is used to define the main content of a page — the part that directly relates to the central topic or functionality of the document. It helps both developers and assistive technologies (like screen readers) identify what the primary content is, improving accessibility and SEO.

Improves Accessibility

Screen readers and other assistive tools can use the <main></main> tag to quickly navigate users to the most important content on the page. Without it, users might have to sift through navigation menus, sidebars, or footers before getting to the core content.

• Helps users skip repetitive content
• Makes websites more navigable for people with disabilities
• Supports ARIA best practices without extra attributes

For example, someone using a screen reader can jump straight to the <main></main> section instead of listening to the entire header and menu every time they load a new page.

Enhances Semantic Structure

HTML5 introduced several semantic elements like <header></header> , <footer></footer> , <nav></nav> , and <main></main> to make web pages more meaningful to browsers and search engines. Using <main></main> clearly separates the central content from secondary areas like ads, sidebars, and headers.

This clarity benefits:

• Search engine crawlers (better understanding of page structure)
• Code maintainability (easier for developers to read and update)
• Responsive design (can help with reorganizing content for mobile)

Just remember: there should only be one <main></main> element per page , and it shouldn't be nested inside <header></header> , <footer></footer> , <aside></aside> , or <nav></nav> .

When Not to Use <main></main>

There are a few cases where you shouldn't use <main></main> . For instance:

• If the content is repeated across multiple pages (like headers, footers, or sidebars)
• In reusable templates or components that aren't specific to one page's main topic
• On pages where the main content is empty or dynamically loaded later

In those cases, stick to
