# --description--

Le classi consentono di utilizzare gli stessi stili CSS su più elementi HTML. Puoi vederlo applicando la tua classe `red-text` al primo elemento `p`.

# --hints--

Il tuo elemento `h2` dovrebbe essere rosso.

```js
assert($('h2').css('color') === 'rgb(255, 0, 0)');
```

Il tuo elemento `h2` dovrebbe avere la classe `red-text`.

```js
assert($('h2').hasClass('red-text'));
```

Il tuo elemento `p` dovrebbe essere rosso.

```js
assert($('p:eq(0)').css('color') === 'rgb(255, 0, 0)');
```

Il secondo e il terzo elemento `p` non dovrebbero essere rossi.

```js
assert(
  !($('p:eq(1)').css('color') === 'rgb(255, 0, 0)') &&
    !($('p:eq(2)').css('color') === 'rgb(255, 0, 0)')
);
```

Il tuo primo elemento `p` dovrebbe avere la classe `red-text`.

```js
assert($('p:eq(0)').hasClass('red-text'));
```
