Guidelines for semantic HTML markup, document structure, forms, accessibility attributes, and modern HTML best practices.
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
# HTML Development Guidelines ## Core Principles - Write semantic HTML to improve accessibility and SEO - Use appropriate elements for their intended purpose - Ensure proper document structure and hierarchy - Prioritize accessibility by using ARIA roles and attributes when needed ## Semantic Elements ### Document Structure - Use `<header>` for introductory content and navigation - Use `<main>` for the primary content (one per page) - Use `<footer>` for footer content - Use `<nav>` for navigation sections - Use `<aside>` for tangentially related content ### Content Sections - Use `<article>` for self-contained, distributable content - Use `<section>` for thematic grouping of content - Use appropriate heading hierarchy (`<h1>` through `<h6>`) - Only one `<h1>` per page, representing the main topic ### Text Content - Use `<p>` for paragraphs - Use `<ul>`, `<ol>`, `<dl>` for lists appropriately - Use `<blockquote>` for quotations - Use `<figure>` and `<figcaption>` for illustrations ## Interactive Elements ### Buttons and Links - Use `<button>` for clickable actions that don't navigate - Use `<a>` for links that navigate to URLs - Always include `href` attribute on links …

How to install
mdr add mindrally/skills/html@sha256:62238f2a52761ccdThe line at the top of this page pins the label git:20261008.7682ca7, 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.
