## Description
Finally, on the `border-bottom` property of `bb2a`, change the `1vw` to `5vh` and change the `#000` color to your `--building-color2` variable. There you go, now it looks good! At any time throughout this project, you can comment out or remove the `border` property you added to everything at the beginning to see what the buildings will look like when that gets removed at the end.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const bb2a = code.match(/\.bb2a\s*{[\s\S]+?[^}]}/g)[0]; assert(/border-bottom\s*:\s*5vh\s+solid\s+var\(\s*--building-color2\s*\)\s*(;|})/g.test(bb2a));
```
