# --description--
The `animation-name` property is used to link a `@keyframes` rule to a CSS selector. The value of this property should match the name of the `@keyframes` rule. Give your `.wheel` selector an `animation-name` property set to `wheel` .
The `animation-duration` property is used to set how long the animation should sequence to complete. The time should be specified in either seconds (`s` ) or milliseconds (`ms` ). Set your `.wheel` selector to have an `animation-duration` property of `10s` .
# --hints--
Your `.wheel` selector should have an `animation-name` property set to `wheel` .
```js
assert(new __helpers.CSSHelp(document).getStyle('.wheel')?.animationName === 'wheel');
```
Your `.wheel` selector should have an `animation-duration` property set to `10s` .
```js
assert(new __helpers.CSSHelp(document).getStyle('.wheel')?.animationDuration === '10s');
```
