# Accessibility
|
|
|
|
## Standard
|
|
WCAG AA compliance minimum. Target AAA where feasible.
|
|
|
|
## Color Contrast
|
|
- Normal text: 4.5:1 minimum ratio
|
|
- Large text (18px+ or 14px+ bold): 3:1 minimum
|
|
- Interactive elements: 3:1 against adjacent colors
|
|
- Test with browser DevTools accessibility panel
|
|
|
|
## Keyboard Navigation
|
|
- All interactive elements focusable via Tab
|
|
- Visible focus indicators on every focusable element (`focus:ring-2`)
|
|
- Escape closes modals, drawers, dropdowns
|
|
- Arrow keys navigate within lists, grids, tabs
|
|
- Enter/Space activates buttons and controls
|
|
- Focus trap inside modals (Tab cycles within modal)
|
|
|
|
## Semantic HTML
|
|
```html
|
|
<header>, <nav>, <main>, <article>, <aside>, <footer>
|
|
```
|
|
Never `<div class="header">`. Use semantic elements.
|
|
|
|
## ARIA
|
|
- Icon-only buttons: `aria-label="Close modal"`
|
|
- Dynamic content: `aria-live="polite"` for updates
|
|
- Screen reader only text: `class="sr-only"`
|
|
- Expandable sections: `aria-expanded="true/false"`
|
|
- Form fields: `aria-describedby` for help text, `aria-invalid` for errors
|
|
|
|
## Images
|
|
- All `<img>` tags need `alt` text
|
|
- Decorative images: `alt=""`
|
|
- Complex images: `aria-describedby` pointing to description
|
|
|
|
## Media
|
|
- Audio/video players: keyboard-accessible controls
|
|
- Provide transcripts/captions when available
|
|
- Respect `prefers-reduced-motion` for animations
|
|
|
|
## Touch Targets
|
|
- Minimum: 44x44px (Apple HIG)
|
|
- Recommended: 48x48px (Material Design)
|
|
- Minimum 8px gap between adjacent targets
|
|
|
|
## Reduced Motion
|
|
```css
|
|
@media (prefers-reduced-motion: reduce) {
|
|
* {
|
|
animation-duration: 0.01ms !important;
|
|
transition-duration: 0.01ms !important;
|
|
}
|
|
}
|
|
```
|
|
Check in JS: `window.matchMedia('(prefers-reduced-motion: reduce)').matches`
|
|
|
|
## Testing
|
|
- VoiceOver (macOS), TalkBack (Android), NVDA (Windows)
|
|
- Keyboard-only navigation test
|
|
- axe DevTools or Lighthouse accessibility audit
|
|
- High contrast mode test
