|
|
|
Dovresti usare la proprietà `z-index` per cambiare il livello dell'elemento.

|
|
|
|
|
|
|
|
```js
|
|
|
|
|
assert.notEmpty(new __helpers.CSSHelp(document).getStyle('.left-mountain')?.zIndex);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Dovresti impostare la proprietà `z-index` su `2`.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
assert.equal(new __helpers.CSSHelp(document).getStyle('.left-mountain')?.zIndex, '2');
|
|
|
|
|
```
|
|
|
|
|
|

|
|
|
Non dovresti cambiare la proprietà `z-index` dell'elemento `.ground`.
