# --description--

It's tough to see now, but there's a border at the edge of your preview, that's the `body`. Create a `div` element in the `body` with a class of `background-buildings`. This will be a container for a group of buildings.

# --hints--

You should create a `div` element.

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

Your `div` element should be within the `body`.

```js
assert(document.querySelector('div')?.parentElement?.localName === 'body');
```

Your `div` element should have a class of `background-buildings`

```js
assert([...document.querySelector('div')?.classList]?.includes('background-buildings'));
```
