# --description--
You want the foreground buildings container to sit directly on top of the background buildings element. Give it a `width` and `height` of `100%`, set the `position` to `absolute`, and the `top` to `0`. This will make it the same size as the body and move the start of it to the top left corner.
# --hints--
You should use a `.foreground-buildings` selector.
```js
assert.exists(new __helpers.CSSHelp(document).getStyle('.foreground-buildings'));
```
You should give the `.foreground-buildings` element a `width` of `100%`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.width, '100%');
```
You should give the `.foreground-buildings` element a `height` of `100%`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.height, '100%');
```
You should give the `.foreground-buildings` element a `position` of `absolute`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.position, 'absolute');
```
You should give the `.foreground-buildings` element a `top` of `0`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.top, '0px');
```
