Nós podemos também alterar o CSS de um elemento HTML diretamente com JQuery.

O jQuery possui uma função chamada `.css()` que o permite alterar o CSS de um elemento.

Aqui está como mudaríamos sua cor para azul:
2021-06-15 00:49:18 -07:00
```js
$("#target1 ").css("color", "blue");
```

Isso é um pouco diferente de uma declaração normal de CSS, porque a propriedade CSS e o seu valor estão entre aspas e separada com vírgula ao invés de ponto e vírgula.

Remova seus seletores de jQuery, deixando uma `document ready function` vazia.

Selecione `target1` e altere sua cor para vermelho.

Seu elemento `target1` deve ter o texto vermelho.
2021-06-15 00:49:18 -07:00
```js
assert($('#target1 ').css('color') === 'rgb(255, 0, 0)');
```

Você deve usar apenas jQuery para adicionar essas classes ao elemento.

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