Accessibility Review

Evaluate designs and implementations against WCAG 2.1 AA standards.

WCAG 2.1 AA Quick Reference

Perceivable

1.1.1 Non-text content has alt text
1.3.1 Info and structure conveyed semantically
1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)
1.4.11 Non-text contrast >= 3:1 (UI components, graphics)

Operable

2.1.1 All functionality available via keyboard
2.4.3 Logical focus order
2.4.7 Visible focus indicator
2.5.5 Touch target >= 44x44 CSS pixels

Understandable

3.2.1 Predictable on focus (no unexpected changes)
3.3.1 Error identification (describe the error)
3.3.2 Labels or instructions for inputs

Robust

4.1.2 Name, role, value for all UI components

Common Issues

Insufficient color contrast
Missing form labels
No keyboard access to interactive elements
Missing alt text on meaningful images
Focus traps in modals
Missing ARIA landmarks
Auto-playing media without controls
Time limits without extension options

Testing Approach

Automated scan (catches ~30% of issues)
Keyboard-only navigation
Screen reader testing (VoiceOver, NVDA)
Color contrast verification
Zoom to 200% — does layout break?
