# --description--

Color-stops allow you to fine-tune where colors are placed along the gradient line. They are used in the `linear-gradient` function to specify where a color ends and the transition to the next color begins. Either a percentage or a length value can be used to define the color-stop position.

For example, in this red-black gradient, the transition from red to black takes place at the 90% point along the gradient line, so red takes up most of the available space:

```css
linear-gradient(90deg, red 90%, black);
```

In the `linear-gradient` function, add a `75%` color stop after the first red color argument. Do not add color stops to the other colors arguments.

# --hints--

Your `.red` CSS rule should have a `background` property set to `linear-gradient(90deg, rgb(255, 0, 0) 75%, rgb(0, 255, 0), rgb(0, 0, 255))`.

```js
assert.include(['linear-gradient(90deg,rgb(255,0,0)75%,rgb(0,255,0),rgb(0,0,255))', 'rgba(0,0,0,0)linear-gradient(90deg,rgb(255,0,0)75%,rgb(0,255,0),rgb(0,0,255))repeatscroll0%0%'], new __helpers.CSSHelp(document).getStyle('.red')?.getPropVal('background', true));
```
