# --description--
Il prossimo edificio avrà tre sezioni. Annida tre elementi `div` all'interno di `.bb4` . Assegna loro le classi `bb4a` , `bb4b` e `bb4c` in quest'ordine.
# --hints--
Dovresti aggiungere tre elementi `div` all'interno di `.bb4` .
```js
assert.equal(document.querySelector("div.bb4")?.children?.length, 3);
```
Dovresti dare al primo nuovo `div` la classe `bb4a` .
```js
assert.exists(document.querySelector("div.bb4 > div.bb4a"));
```
Dovresti dare al secondo `div` la classe `bb4b` .
```js
assert.exists(document.querySelector("div.bb4 > div.bb4a"));
```
Dovresti dare al terzo nuovo `div` la classe `bb4c` .
```js
assert.exists(document.querySelector("div.bb4 > div.bb4a"));
```
Dovresti posizionare i nuovi elementi `div` in questo ordine `.bb4a + .bb4b + .bb4c` .
```js
assert.exists(document.querySelector("div.bb4a + div.bb4b"));
assert.exists(document.querySelector("div.bb4b + div.bb4c"));
```
