# --description--
Gradients can use as many colors as you want like this:
```css
gradient-type(
color1,
color2,
color3
);
```
Add a `linear-gradient` to `.bb1d` with `orange` as the first color, `--building-color1` as the second, and `--window-color1` as the third. Remember to use the gradient on the `background` property.
# --hints--
You should use the `background` on `.bb1d`.
```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('.bb1d')?.background);
```
You should give the `background` property a `linear-gradient`.
```js
assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.background, 'linear-gradient');
```
You should use `orange` as the first color in the `linear-gradient`.
```js
assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange');
```
You should use `--building-color1` as the second color in the `linear-gradient`.
```js
assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange,var(--building-color1)');
```
You should use `--window-color1` as the third color in the `linear-gradient`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange,var(--building-color1),var(--window-color1))');
```
