## Description
Next, remove the `width` and `height` from `bb2a`, and change the `border-left` and `border-right` to use `5vw` instead of `1vw`. The element will now have zero size and the borders will come together in the middle.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const bb2a = code.match(/\.bb2a\s*{[\s\S]+?[^}]}/g)[0]; assert(!/width/g.test(bb2a) && !/height/g.test(bb2a) && /border-left\s*:\s*5vw\s+solid\s+#999\s*(;|})/g.test(bb2a) && /border-right\s*:\s*5vw\s+solid\s+#999\s*(;|})/g.test(bb2a));
