Detailed patterns and worked examples
Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
Best Practices
- Use Semantic HTML: Prefer native elements over ARIA when possible
- Test with Real Users: Include people with disabilities in user testing
- Keyboard First: Design interactions to work without a mouse
- Don't Disable Focus Styles: Style them, don't remove them
- Provide Text Alternatives: All non-text content needs descriptions
- Support Zoom: Content should work at 200% zoom
- Announce Changes: Use live regions for dynamic content
- Respect Preferences: Honor prefers-reduced-motion and prefers-contrast
Common Issues
- Missing alt text: Images without descriptions
- Poor color contrast: Text hard to read against background
- Keyboard traps: Focus stuck in component
- Missing labels: Form inputs without associated labels
- Auto-playing media: Content that plays without user initiation
- Inaccessible custom controls: Recreating native functionality poorly
- Missing skip links: No way to bypass repetitive content
- Focus order issues: Tab order doesn't match visual order
Testing Tools
- Automated: axe DevTools, WAVE, Lighthouse
- Manual: VoiceOver (macOS/iOS), NVDA/JAWS (Windows), TalkBack (Android)
- Simulators: NoCoffee (vision), Silktide (various disabilities)
