|
Infine, crea un nuovo selettore `75%` tra i tuoi selettori `50%` e `100%`. 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');
|
||
|
|
```
|
||
|
|
