Instructions

  1. Review design specifications for accessibility
  2. Check color contrast ratios
  3. Verify keyboard navigation support
  4. Check screen reader compatibility

Examples

Input: Review design for accessibility Output:

### Accessibility Review

**Overall Compliance:** WCAG 2.1 Level AA ✓

**Color Contrast:**
- Primary text on white: 4.5:1 ✓ (WCAG AA)
- Secondary text on white: 4.2:1 ✗ (needs improvement)
- Large text on primary: 3.1:1 ✓ (WCAG AA)
- Recommendation: Increase secondary text contrast to 4.5:1

**Keyboard Navigation:**
- All interactive elements keyboard accessible ✓
- Focus indicators visible ✓
- Tab order logical ✓
- Skip links present ✓

**Screen Reader Support:**
- Semantic HTML structure ✓
- ARIA labels where needed ✓
- Alt text for images ✓
- Form labels properly associated ✓

**Touch Targets:**
- All interactive elements ≥ 44x44px ✓
- Adequate spacing between touch targets ✓

**Text Resizing:**
- Design works at 200% zoom ✓
- No horizontal scrolling required ✓

**Issues Found:**
1. Secondary text contrast below 4.5:1 (should be improved)
2. Missing ARIA label on icon-only button (needs label)

**Recommendations:**
- Increase secondary text color darkness
- Add aria-label="Close" to icon button

Accessibility Areas to Check

  • Color Contrast: Text/background contrast ratios (WCAG AA: 4.5:1)
  • Keyboard Navigation: All interactive elements keyboard accessible
  • Focus Indicators: Visible focus states
  • Screen Reader Support: Semantic HTML, ARIA labels, alt text
  • Touch Targets: Minimum 44x44px for mobile
  • Text Resizing: Works at 200% zoom
  • Reading Order: Logical content order
  • Form Labels: Properly associated labels
  • Error Messages: Accessible error communication
  • Skip Links: Skip navigation links

WCAG Compliance Levels

  • Level A: Basic accessibility (minimum)
  • Level AA: Standard compliance (recommended)
  • Level AAA: Enhanced accessibility (ideal)

Common Issues

  • Low Contrast: Text/background contrast too low
  • Missing Alt Text: Images without descriptive alt text
  • Missing Labels: Form inputs without labels
  • Small Touch Targets: Interactive elements too small
  • No Focus Indicators: Missing visible focus states
  • Poor Semantic Structure: Incorrect HTML structure
  • Keyboard Traps: Elements that trap keyboard focus
