Check Accessibility

Verify that components meet WCAG 2.1 AA accessibility standards.

When to Use

• User wants to check accessibility
• User mentions "a11y", "accessibility", or "WCAG"
• Component has accessibility issues
• Before submitting a PR

Instructions

1. Automated Testing:

   # Test all components
   npm run test:a11y
   
   # Test specific component(s)
   npm run test:a11y -- tabs
   npm run test:a11y -- tabs button card
   
   # Combine with Playwright options
   npm run test:a11y -- tabs --workers 1
   

   This runs Playwright tests with @axe-core/playwright for automated accessibility checks. You can test specific components by passing their names as arguments after --. Component names are case-insensitive and should match the keys in e2e/a11y/routes/components.ts.

2. Manual Checks:

   • Verify semantic HTML elements
   • Check ARIA attributes are correct
   • Test keyboard navigation
   • Verify focus management
   • Test with screen readers

3. Common Accessibility Requirements:

   • All interactive elements must be keyboard accessible
   • Proper ARIA labels and roles
   • Focus indicators visible
   • Color contrast meets WCAG AA (4.5:1 for text)
   • Semantic HTML structure

4. Testing Tools:

   • @axe-core/playwright for automated testing
   • @testing-library/react for unit test accessibility
   • Browser DevTools Accessibility panel
   • Screen reader testing (NVDA, JAWS, VoiceOver)

5. Fix Issues:

   • Add missing ARIA attributes
   • Fix keyboard navigation
   • Improve focus management
   • Fix color contrast
   • Use semantic HTML
