# --description--
Agora dê à regra `@keyframes wheel` um seletor de `100%`. Dentro disso, defina `transform` para `rotate(360deg)`. Ao fazer isso, sua animação completará uma rotação inteira.
# --hints--
Sua regra `@keyframes wheel` deve ter um seletor de `100%`.
```js
const rules = new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules
assert(rules?.[0]?.keyText === '100%' || rules?.[1]?.keyText === '100%');
```
O elemento `100%` deve vir depois do elemento `0%`.
```js
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules?.[1]?.keyText === '100%')
```
O seletor `100%` deve ter a propriedade `transform` definida para `rotate(360deg)`.
```js
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.cssRules?.[1]?.style?.transform === 'rotate(360deg)')
```
