Core Principles
- Semantic HTML first — Use native elements before ARIA
- Keyboard accessible — All interactions work without a mouse
- Focus visible — Clear indication of current focus
- Name, Role, Value — Every control has accessible name, correct role, exposed state
- Announce changes — Dynamic content updates reach screen readers
Common Issues (Quick Fixes)
| Issue | Fix |
|---|---|
| Icon button no name | Add aria-label |
| Custom control no role | Add appropriate role attribute |
| Focus outline removed | Use focus-visible instead |
| Toggle state unclear | Use aria-pressed or aria-expanded |
| Dynamic content silent | Add live region with aria-live |
| Click-only handler | Add keydown for Enter/Space |
Anti-Patterns
❌ Never do these:
- Remove focus outlines without replacement
- Use
tabindex > 0 - Rely solely on color to convey information
- Auto-focus without user intent
- Trap focus unintentionally
- Use ARIA where native HTML suffices
- Change
aria-labelto convey state (usearia-pressed)
Next Steps

- For focus management: focus.md
- For ARIA roles and states: aria.md
- For React-specific patterns: react.md
