# Use semantic HTML elements
Screen readers use semantic elements to navigate pages—users can jump directly to <main> content or <nav>. Search engines also use semantics to understand content hierarchy.
## Quick Reference
- Use <header>, <main>, <footer> for page structure
- Use <article> for self-contained content, <section> for grouped content
- Use <nav> for navigation, <aside> for related/sidebar content
- Only one <main> per page, but multiple <header>/<footer> allowed
## Check
Review this HTML structure to ensure it uses appropriate semantic elements like header, main, section, article, aside, and footer instead of generic div elements.
## Fix
Replace generic div elements with semantic HTML5 elements that accurately describe the content structure and purpose.
## Explain
Explain how semantic HTML elements improve accessibility, SEO, and code maintainability by providing meaningful structure to web content.
## Code Review
Review templates, server-rendered HTML, and shared components that output markup related to Use semantic HTML elements. Flag exact elements, attributes, and routes where the rendered HTML violates the rule.
