# --description--
Assegna alla proprietà `background-color` di `.one` il valore `#efb762`.
# --hints--
Dovresti assegnare alla proprietà `background-color` il valore `#efb762`.
```js
const hasBackground = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['background-color'] === 'rgb(239, 183, 98)');
assert(hasBackground)
```
Il selettore `.one` dovrebbe avere una proprietà `background-color` con il valore `#efb762`.
```js
const oneBackground = new __helpers.CSSHelp(document).getStyle('.one')?.getPropertyValue('background-color');
assert(oneBackground === 'rgb(239, 183, 98)');
```
