Use when reviewing templates, rendered HTML, or shared components related to Use semantic HTML elements. Validate the final browser-facing markup, not just the source framework abstraction.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. --- …

How to install
mdr add thedaviddias/front-end-checklist/html5-semantic-elements@sha256:7cfe73c3fe29b40bThe line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
