# --description--
Now give the `@keyframes wheel` rule a `100%` selector. Within that, set the `transform` to `rotate(360deg)`. By doing this, your animation will now complete a full rotation.
# --hints--
Your `@keyframes wheel` rule should have a `100%` selector.
```js
const rules = new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules
assert(rules?.[0]?.keyText === '100%' || rules?.[1]?.keyText === '100%');
```
Your `100%` selector should come after your `0%` selector.
```js
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules?.[1]?.keyText === '100%')
```
Your `100%` selector should have a `transform` property set to `rotate(360deg)`.
```js
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules?.[1]?.style?.transform === 'rotate(360deg)')
```
