# --description--
|
|
|
|
Ora seleziona l'elemento `#piano` con un selettore di `id`. Imposta `background-color` a `#00471b`, `width` a `992px` e `height` a `290px`.
|
|
|
|
# --hints--
|
|
|
|
Dovresti avere un selettore `#piano`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('#piano'));
|
|
```
|
|
|
|
Il selettore `#piano` dovrebbe avere la proprietà `background-color` impostata a `#00471b`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.backgroundColor === 'rgb(0, 71, 27)');
|
|
```
|
|
|
|
Il selettore `#piano` dovrebbe avere una proprietà `width` impostata su `992px`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.width === '992px');
|
|
```
|
|
|
|
Il selettore `#piano` dovrebbe avere una proprietà `height` impostata su `290px`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.height === '290px');
|
|
```
