# --description--
|
|
|
|
You can make an instant color change in a gradient by giving the transition zero space like this:
|
|
|
|
```css
|
|
gradient-type(
|
|
color1,
|
|
color1 50%,
|
|
color2 50%,
|
|
color2
|
|
);
|
|
```
|
|
|
|
Here, the top half of the element will be `color1` and the bottom half will be `color2`. Add a `linear-gradient` to `.bb2b` that uses `--building-color2` from `0%` to `6%` and `--window-color2` from `6%` to `9%`.
|
|
|
|
# --hints--
|
|
|
|
You should give `.bb2b` a `background` property.
|
|
|
|
```js
|
|
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle(`.bb2b`)?.background);
|
|
```
|
|
|
|
You should use a `linear-gradient` on the `background`.
|
|
|
|
```js
|
|
assert.include(new __helpers.CSSHelp(document).getStyle(`.bb2b`)?.background, "linear-gradient");
|
|
```
|
|
|
|
You should use `--building-color2` from `0%` to `6%`.
|
|
|
|
```js
|
|
assert.match(new __helpers.CSSHelp(document).getStyle(`.bb2b`)?.getPropVal('background', true), /var\(--building-color2\)(0%)?,var\(--building-color2\)6%/);
|
|
```
|
|
|
|
You should use `--window-color2` from `6%` to `9%`.
|
|
|
|
```js
|
|
assert.include(new __helpers.CSSHelp(document).getStyle(`.bb2b`)?.getPropVal('background', true), "var(--window-color2)6%,var(--window-color2)9%");
|
|
```
|
|
|
|
`.bb2b` should have a `linear-gradient` transitioning from `--building-color2` at `0%` to `6%`, and `--window-color2` at `6%` to `9%`.
|
|
|
|
```js
|
|
assert.match(new __helpers.CSSHelp(document).getStyle(`.bb2b`)?.getPropVal('background', true), /linear-gradient\(var\(--building-color2\)(0%)?,var\(--building-color2\)6%,var\(--window-color2\)6%,var\(--window-color2\)9%\)/);
|
|
```
