# --description--
Give the `.key.black--key::after` a `position` property set to `absolute` and a `left` property set to `-18px`.
# --hints--
Your `.key.black--key::after` selector should have a `position` property set to `absolute`.
```js
assert(new __helpers.CSSHelp(document).getStyle('.key.black--key::after')?.position === 'absolute');
```
Your `.key.black--key::after` selector should have a `left` property set to `-18px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('.key.black--key::after')?.left === '-18px');
```
