# --description--
Change the stack level of the `.penguin-head` element such that it appears in front of the `.penguin-body` element.
# --hints--
You should use the `z-index` property to change the stack level.
```js
assert.notEmpty(new __helpers.CSSHelp(document).getStyle('.penguin-head')?.zIndex);
```
You should give the `.penguin-head` element a `z-index` of `1`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.penguin-head')?.zIndex, '1');
```
