## Description
You don't need the `height` or `background-color` properties in `bb1a`, `bb1b` or `bb1c` anymore, so go ahead and remove them.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const bb1aStyle = code.match(/\.bb1a\s*{[\s\S]+?[^}]}/g)[0]; const bb1bStyle = code.match(/\.bb1b\s*{[\s\S]+?[^}]}/g)[0]; const bb1cStyle = code.match(/\.bb1c\s*{[\s\S]+?[^}]}/g)[0]; assert(!/(height|background-color)/g.test(bb1aStyle) && !/(height|background-color)/g.test(bb1bStyle) && !/(height|background-color)/g.test(bb1cStyle));
```
