--description--

我们也能用 jQuery 直接改变 HTML 标签的 CSS。

jQuery 有一个.css()方法，其能改变标签的 CSS。

下面的代码效果是把颜色变蓝：

$("#target1").css("color", "blue");

这与通常的 CSS 声明略有不同，因为这个 CSS 属性和它的值在英文引号里，并且它们用逗号而不是冒号间隔开。

删除你的jQuery选择器，并留下空的document ready function。

请选择target1并将其颜色变为红色（red）。

--hints--

target1标签应该有红色文本。

assert($('#target1').css('color') === 'rgb(255, 0, 0)');

仅用 jQuery 给标签添加类。

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

  });
