# --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.
# --hints--
test-text
```js
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)
);
