# --description--
Rimuovi `orange` dal gradiente di `.bb1d` e cambia `80%` in `50%` . Questo farà sì che la transizione tra `--building-color1` e `--window-color1` avvenga a metà dell'elemento.
# --hints--
Dovresti rimuovere `orange` da `linear-gradient` .
```js
assert.notInclude(new __helpers.CSSHelp(document).getStyle('.bb1d')?.background, 'orange');
```
Dovresti cambiare l'attuale primo colore del `linear-gradient` per far avvenire la transizione al `50%` .
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(var(--building-color1)50%,var(--window-color1))');
```
