# --description--
|
|
|
|
Time to style the keys. Below the `#piano` rule, target the `.keys` element with a `class` selector. Give the new rule a `background-color` property of `#040404`, a `width` property of `949px` and a `height` property of `180px`.
|

# --hints--

|
|
You should have a `.keys` selector.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('.keys'));
|
|
```
|
|
|
|
Your `.keys` selector should have a `background-color` property set to `#040404`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('.keys')?.backgroundColor === 'rgb(4, 4, 4)');
|
|
```
|
|
|
|
Your `.keys` selector should have the `width` property set to `949px`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('.keys')?.width === '949px');
|
|
```
|
|
|
|
Your `.keys` selector should have a `height` property set to `180px`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('.keys')?.height === '180px');
|
|
```
