Possiamo anche cambiare direttamente il CSS di un elemento HTML con jQuery.

jQuery ha una funzione chiamata `.css()` che consente di cambiare il CSS di un elemento.

Ecco come potremmo cambiare il suo colore in blu:
2021-06-15 00:49:18 -07:00
```js
$("#target1 ").css("color", "blue");
```

Questo è leggermente diverso da una normale dichiarazione CSS, perché la proprietà CSS e il suo valore sono tra virgolette e separati da una virgola invece che dai due punti.

Elimina i tuoi selettori jQuery, lasciando una `document ready function` vuota.

Seleziona `target1` e cambia il suo colore in rosso.

Il tuo elemento `target1` dovrebbe avere un testo rosso.
2021-06-15 00:49:18 -07:00
```js
assert($('#target1 ').css('color') === 'rgb(255, 0, 0)');
```

Dovresti usare solo jQuery per aggiungere queste classi all'elemento.

```js
assert(!code.match(/class.*animated/g));
```
