What problem does it solve?

This Skill provides 30 pragmatic rules for production HTML that prioritize semantic markup, accessibility (WCAG 2.1 AA), performance, forms, and security. It helps teams produce robust, search-friendly, and accessible markup with confidence, reducing repetitive reviews and fixes.

Core Features & Use Cases

  • Semantic Structure: enforce proper element choices (article, header, nav, main) for meaningful document outlines.
  • Accessibility & WCAG: recommended patterns for ARIA attributes, alt text, landmarks, and skip links.
  • Performance & SEO Guidance: guidelines to improve Core Web Vitals and search visibility.

Quick Start

Use this skill to audit a page: confirm heading order, replace generic divs with semantic elements, add descriptive alt text for images, and implement skip links for keyboard navigation.
