# --description--
Remove `orange` from the `bb1d` gradient and change the `80%` to `50%`. This will make `--building-color1` solid for the top half, and then transition to `--window-color1` for the bottom half.
# --hints--
test-text
```js
const bb1d = code.match(/\.bb1d\s*{[\s\S]+?[^}]}/g)[0];
assert(
/background\s*:\s*linear-gradient\(\s*var\(\s*--building-color1\s*\)\s*50%\s*,\s*var\(\s*--window-color1\s*\)\s*\)\s*(;|})/g.test(
bb1d
)
);
