## Custom Animations (v4.1+)

```css
/* In your CSS with @theme */
@theme {
  --animate-fade-in: fadeIn 0.5s ease-in-out;
  --animate-slide-up: slideUp 0.3s ease-out;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}

@keyframes slideUp {
  from {
    opacity: 0;
    transform: translateY(20px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}
```

Usage:

```html
<div class="animate-fade-in">Fades in on load</div>
<div class="animate-slide-up">Slides up on load</div>
```

---

## 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;
  }
}
```
