|
|
|
|
|
Per creare uno scenario sullo sfondo, aggiungerai due montagne.
|
|
|
|
|
|
|
|
|
|
Sopra l'elemento `.penguin`, aggiungi un `div` con un attributo `class` di `left-mountain`.
|
|

Dovresti aggiungere un nuovo `div` all'interno di `body`. Dovrebbe esserci `--fcc-expected--` elementi `div` invece di `--fcc-actual--`.

|
|
|
|
|
```js
|
|
|
|
|
assert.equal(document.querySelectorAll('body > div')?.length, 3);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Dovresti dare all'elemento `div` un attributo `class` di `left-mountain`.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
assert.include(document.querySelector('body > div:not(.ground, .penguin)')?.className, 'left-mountain');
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Dovresti inserire `.left-mountain` prima di `.penguin`.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
assert.strictEqual(document.querySelector('.penguin')?.previousElementSibling, document.querySelector('.left-mountain'));
|
|
|
|
|
```
