Accessibility Auditor

Overview

Audits web pages and UI components against WCAG 2.2 (Level AA) success criteria. Identifies violations in color contrast, keyboard navigation, ARIA usage, semantic HTML, form labeling, focus management, and dynamic content updates. Produces actionable fixes with exact code changes.

Instructions

When asked to audit accessibility:

1. Determine the scope:

   • Single component, full page, or entire application?
   • Target compliance level: A, AA (default), or AAA?
   • Any specific regulations: EAA (European Accessibility Act), ADA, Section 508?

2. Check semantic structure (WCAG 1.3.1, 1.3.2):

   • Heading hierarchy: h1 → h2 → h3, no skipped levels
   • Landmark regions: <nav>, <main>, <header>, <footer>, <aside>
   • Lists use <ul>/<ol>/<dl>, not styled <div>s
