## Motion Preferences
|
|
|
|
Respect user's motion preferences:
|
|
|
|
```html
|
|
<!-- Disable animations for users who prefer reduced motion -->
|
|
<div class="transform transition-transform motion-reduce:transition-none">
|
|
Doesn't animate when user prefers reduced motion
|
|
</div>
|
|
|
|
<!-- Only animate when motion is preferred -->
|
|
<div class="animate-pulse motion-safe:hover:animate-spin">
|
|
Only animates when motion is preferred
|
|
</div>
|
|
```
|
|
|
|
### Global Reduced Motion Support
|
|
|
|
```css
|
|
@media (prefers-reduced-motion: reduce) {
|
|
*,
|
|
*::before,
|
|
*::after {
|
|
animation-duration: 0.01ms !important;
|
|
animation-iteration-count: 1 !important;
|
|
transition-duration: 0.01ms !important;
|
|
}
