Target the `.left-mountain` element, and set its `width` and `height` to `300px`. Then, set the `background` to a linear gradient starting at `rgb(203, 241, 228)` and ending at `rgb(80, 183, 255)`.
# --hints--
You should use the `.left-mountain` selector.
```js
assert.match(code, /\.left-mountain\s*\{/);
```
You should give `.left-mountain` a `width` of `300px`. Expected `--fcc-actual--` to be `--fcc-expected--`.
assert.include(['linear-gradient(rgb(203,241,228),rgb(80,183,255))', 'rgba(0,0,0,0)linear-gradient(rgb(203,241,228),rgb(80,183,255))repeatscroll0%0%'], new __helpers.CSSHelp(document).getStyle('.left-mountain')?.getPropVal('background', true));
