## Description
< section id = 'description' >
I don't like how spaced out the buildings are. Squeeze them together by adding two empty `div` elements to the top of the `background-buildings` element, two more at the bottom of it, and one more in between `bb3` and `bb4` . These will be added as things that are spaced evenly across the container, effectively moving the buildings closer to the center.

```yml
tests:
- text: test-text
testString: const bb = $(".background-buildings").children("div"); assert(bb.length === 9 & & bb[2] === $("div.bb1")[0] & & bb[3] === $("div.bb2")[0] & & bb[4] === $("div.bb3")[0] & & bb[6] === $("div.bb4")[0]);
