# --description--
Crea alcuni "pallini" per lo strumento. Aggiungi cinque elementi `div` all'interno dell'elemento `gray-instrument` . Imposta l'attributo `class` di ciascuno su `black-dot` .
# --hints--
Dovresti avere cinque nuovi elementi `div` all'interno dell'elemento `#gray-instrument` .
```js
assert(document.querySelectorAll('#gray-instrument div').length === 5);
```
Tutti e cinque gli elementi `div` dovrebbero avere la classe `black-dot` .
```js
assert(document.querySelectorAll('#gray-instrument .black-dot').length === 5);
```
