# --description--
Now set the `height` for `.one` to 150 pixels.
# --hints--
You should set the `height` property to `150px`.
```js
const hasHeight = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.height === '150px');
assert(hasHeight);
```
Your `.one` element should have a `height` value of `150px`.
```js
const oneHeight = new __helpers.CSSHelp(document).getStyle('.one')?.getPropertyValue('height');
assert(oneHeight === '150px');
```
