# --description--

The corners of each rectangle are still too sharp.

Round each corner of the `.one` element by 9 pixels, using the `border-radius` property.

# --hints--

You should set the `border-radius` property to `9px`.

```js
const hasBorderRadius = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['border-radius'] === '9px');
assert(hasBorderRadius);
```

Your `.one` element should have a `border-radius` value of `9px`.

```js
const oneBorderRadius =new __helpers.CSSHelp(document).getStyle('.one')?.getPropertyValue('border-radius');
assert(oneBorderRadius === '9px');
```
