# --description--
Using an id selector, style the element with the id `gray-mask`. Give it a `width` of `150px`, a `height` of `150px`, and a `background-color` of `rgb(167, 162, 117)`.
# --hints--
You should have a `#gray-mask` selector.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask'));
```
Your `#gray-mask` selector should have a `width` property set to `150px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.height === '150px');
```
Your `#gray-mask` selector should have a `height` property set to `150px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.height === '150px')
```
Your `#gray-mask` selector should have a `background-color` property set to `rgb(167, 162, 117)`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.backgroundColor === 'rgb(167, 162, 117)');
```
