# --description--
You don't always have to use pixels when sizing an element.
Create a new rule, `.three`, and set its `width` to `91%`.
# --hints--
You should use the `.three` selector.
```js
const hasThree = new __helpers.CSSHelp(document).getStyle('.three');
assert(hasThree);
```
You should set the `width` property to `91%`.
```js
const hasWidth = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.width === '91%');
assert(hasWidth);
```
Your `.three` element should have a `width` value of `91%`.
```js
const threeWidth = new __helpers.CSSHelp(document).getStyle('.three')?.getPropertyValue('width');
assert(threeWidth === '91%');
```
