# --description--

Change the stack level of the `.penguin` element such that it appears in front of the `.ground` element, and give it a `position` of `relative`.

# --hints--

You should use the `z-index` property to change the stack level.

```js
assert.notEmpty(new __helpers.CSSHelp(document).getStyle('.penguin')?.zIndex);
```

You should give the `.penguin` element a `z-index` of `4`.

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.penguin')?.zIndex, '4');
```

You should give `.penguin` a `position` property.

```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('.penguin')?.position);
```

You should give `.penguin` a `position` of `relative`.

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.penguin')?.position, 'relative');
```
