# --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');
|
|
|
|
|
```
