# --description--

The background buildings are starting to look pretty good. Create a new `div` below the `background-buildings` element and give it a class of `foreground-buildings`. This will be another container for more buildings.

# --hints--

You should create a new `div` element.

```js
assert.equal(document.querySelectorAll('div')?.length, 15);
```

The new `div` should come after the `div.background-buildings` element.

```js
assert.exists(document.querySelector('div.background-buildings + div'));
```

Your new `div` should have a class of `foreground-buildings`.

```js
assert.exists(document.querySelector('div.foreground-buildings'));
```
