# --description--

The ears should always be placed above the part of the head it overlaps. You can do this with the `z-index` property.

`z-index` is a property you can use to define the order of overlapping HTML elements. Any element with a higher `z-index` will always be positioned over an element with a lower `z-index`.

To see `z-index` in action, set the `z-index` property of the left ear to `-1`.

# --hints--

Your `.cat-left-ear` selector should have a `z-index` of `-1`. Don't forget to add a semicolon.

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.cat-left-ear')?.zIndex, '-1')
```
