# --description--
Now target your `#piano` element with an `id` selector. Set `background-color` property to `#00471b`, the `width` property to `992px` and the `height` property to `290px`.
# --hints--
You should have a `#piano` selector.
```js
assert(new __helpers.CSSHelp(document).getStyle('#piano'));
```
Your `#piano` selector should have the `background-color` property set to `#00471b`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.backgroundColor === 'rgb(0, 71, 27)');
```
Your `#piano` selector should have a `width` property set to `992px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.width === '992px');
```
Your `#piano` selector should have the `height` set to `290px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.height === '290px');
```
