# --description--

Create a new `.large` selector and give it a `height` property set to `10px`. Also create an `.large, .medium` selector and set the `background-color` property to `black`.

# --hints--

You should have a new `.large` selector.

```js
assert(new __helpers.CSSHelp(document).getStyle('.large'));
```

Your `.large` selector should have a `height` property set to `10px`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.large')?.height === '10px');
```

You should have a new `.large, .medium` selector.

```js
assert(new __helpers.CSSHelp(document).getStyle('.large, .medium'));
```

Your `.large, .medium` selector should have a `background-color` property set to `black`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.large, .medium')?.backgroundColor === 'black');
```
