Dai a questo nuovo selettore una proprietà `background-color` impostata su `yellow.` Con questo, la tua animazione è molto più fluida e la ruota panoramica è completa. # --hints-- Dovresti creare un nuovo selettore `75%` nella tua regola `@keyframes cabins`. ```js const rules = new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules; assert(rules?.[0]?.keyText === '75%' || rules?.[1]?.keyText === '75%' || rules?.[2]?.keyText === '75%' || rules?.[3]?.keyText === '75%' || rules?.[4]?.keyText === '75%'); ``` Il tuo selettore `75%` dovrebbe essere compreso tra i selettori `50%` e `100%`. ```js assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules?.[3]?.keyText === '75%'); ``` Il tuo selettore `75%` dovrebbe avere una proprietà `background-color` impostata a `yellow`. ```js assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[1]?.cssRules?.[3]?.style?.backgroundColor === 'yellow'); ``` # --seed-- ## --seed-contents-- ```html Ferris Wheel
