# --description--
Position the `gray-mask` by setting `position` to `absolute`, the `top` to `-10px`, and the `left` to `70px`.
# --hints--
Your `#gray-mask` selector should have a `position` property set to `absolute`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.position === 'absolute');
```
Your `#gray-mask` selector should have a `top` property set to `-10px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.top === '-10px');
```
Your `#gray-mask` selector should have a `left` property set to `70px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('#gray-mask')?.left === '70px');
