This will apply in the middle of the animation cycle. Set the `background-color` to `purple`. # --hints-- You should create a new `50%` selector in your `@keyframes cabins` rule. ```js const rules = new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules; assert(rules?.[0]?.keyText === '50%' || rules?.[1]?.keyText === '50%' || rules?.[2]?.keyText === '50%'); ``` Your `50%` selector should be between your `0%` and `100%` selectors. ```js assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules?.[1]?.keyText === '50%'); ``` Your `50%` selector should have a `background-color` property set to `purple`. ```js assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules?.[1]?.style?.backgroundColor === 'purple'); ``` # --seed-- ## --seed-contents-- ```html Ferris Wheel
