# --description--
For `fb2a`, add a `border-bottom` of `10vh solid var(--building-color3)` and a `border-left` and `border-right` of `1vw solid transparent`. This time the border trick will create a trapezoid shape.
# --hints--
test-text
```js
const fb2a = code.match(/\.fb2a\s*{[\s\S]+?[^}]}/g)[0];
assert(
/border-bottom\s*:\s*10vh\s+solid\s+var\(\s*--building-color3\s*\)\s*(;|})/g.test(
fb2a
) &&
/border-left\s*:\s*1vw\s+solid\s+transparent\s*(;|})/g.test(fb2a) &&
/border-right\s*:\s*1vw\s+solid\s+transparent\s*(;|})/g.test(fb2a)
);
