bad87fee1348bd9aecf08806	使用 class 选择器设置单个元素的样式	0	https://scrimba.com/c/c2MvDtV	18337	use-a-css-class-to-style-an-element

--description--

CSS 的 class 具有可重用性，可应用于各种 HTML 元素。

一个 CSS class 声明示例如下所示：

<style>
  .blue-text {
    color: blue;
  }
</style>

可以看到，我们在 <style> 样式声明区域里，创建了一个名为 blue-text 的 class 选择器。你可以将 CSS class 添加到一个 HTML 元素里，如下所示：<h2 class="blue-text">CatPhotoApp</h2>

**注意：**在 style 样式区域声明里，class 需以 . 开头。而在 HTML 元素里，class 属性的前面不能添加 .。

--instructions--

在 style 样式声明里，把 h2 元素选择器改为 .red-text class 选择器，同时将颜色 blue 改为 red。

在 h2 元素里，添加一个 class，值为 'red-text'。

--hints--

h2 元素应为红色。

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

h2 元素应含有 red-text class。

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

style 样式声明区域里应该包含一个 red-text class 选择器，且它的颜色应为红色。

assert(code.match(/\.red-text\s*\{\s*color\s*:\s*red;\s*\}/g));

不应在 h2 元素里使用行内样式 style="color: red"。

assert($('h2').attr('style') === undefined);

--seed--

--seed-contents--

<style>
  h2 {
    color: blue;
  }
</style>
