# --description--
You don't need the `height` or `background-color` properties in `bb1a`, `bb1b` or `bb1c` anymore, so go ahead and remove them.
# --hints--
test-text
```js
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)
);
