# --description--
Give the `fb4-window` elements a `width` of `30%`, `height` of `10%`, and `border-radius` of `50%`. These will make some circular windows for this building.
# --hints--
test-text
```js
const fb4w = code.match(/\.fb4-window\s*{[\s\S]+?[^}]}/g)[0];
assert(
/width\s*:\s*30%\s*(;|})/g.test(fb4w) &&
/height\s*:\s*10%\s*(;|})/g.test(fb4w) &&
/border-radius\s*:\s*50%\s*(;|})/g.test(fb4w)
);
