## 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.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const fb = code.match(/\.foreground-buildings\s*{[\s\S]+?[^}]}/g)[0]; assert($(".foreground-buildings").css("position") === "absolute" && $(".foreground-buildings").css("top") === "0px" && /width\s*:\s*100%\s*(;|})/g.test(fb) && /height\s*:\s*100%\s*(;|})/g.test(fb));
```
