# --description--
Target the `.ground` element, and set its `width` to take up the full width of the viewport. Then, set the `height` to `400px`.
# --hints--
You should use the `.ground` selector.
```js
assert.match(code, /\.ground\s*\{/);
```
You should give the `.ground` element a `width` of `100vw`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.ground')?.width, '100vw');
```
You should give the `.ground` element a `height` of `400px`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.ground')?.height, '400px');
```
