## Animate SVG Wrapper Instead of SVG Element
|
|
|
|
Many browsers don't have hardware acceleration for CSS3 animations on SVG elements. Wrap SVG in a `<div>` and animate the wrapper instead.
|
|
|
|
**Incorrect (animating SVG directly - no hardware acceleration):**
|
|
|
|
```tsx
|
|
function LoadingSpinner() {
|
|
return (
|
|
<svg
|
|
className="animate-spin"
|
|
width="24"
|
|
height="24"
|
|
viewBox="0 0 24 24"
|
|
>
|
|
<circle cx="12" cy="12" r="10" stroke="currentColor" />
|
|
</svg>
|
|
)
|
|
}
|
|
```
|
|
|
|
**Correct (animating wrapper div - hardware accelerated):**
|
|
|
|
```tsx
|
|
function LoadingSpinner() {
|
|
return (
|
|
<div className="animate-spin">
|
|
<svg
|
|
width="24"
|
|
height="24"
|
|
viewBox="0 0 24 24"
|
|
>
|
|
<circle cx="12" cy="12" r="10" stroke="currentColor" />
|
|
</svg>
|
|
</div>
|
|
)
|
|
}
|
|
```
|
|
|
|
This applies to all CSS transforms and transitions (`transform`, `opacity`, `translate`, `scale`, `rotate`). The wrapper div allows browsers to use GPU acceleration for smoother animations.
