## Description
|
|||
|
<section id="description">我们的“粉红色文本”类覆盖了我们的<code>body</code>元素的CSS声明!我们刚刚证明我们的类将覆盖<code>body</code>元素的CSS。所以下一个合乎逻辑的问题是,我们可以做些什么来覆盖我们的<code>pink-text</code>类? </section>
|
|||
|
|
|||
|
## Instructions
|
|||
|
<section id="instructions">创建一个名为<code>blue-text</code>的附加CSS类,它为元素提供蓝色。确保它低于<code>pink-text</code>类声明。除了<code>pink-text</code>类之外,将<code>blue-text</code>类应用于<code>h1</code>元素,让我们看看哪个获胜。将多个类属性应用于HTML元素是通过它们之间的空格完成的,如下所示: <code>class="class1 class2"</code>注意:HTML元素中列出的类的顺序无关紧要。但是, <code><style></code>部分中的<code>class</code>声明的顺序是重要的。第二个声明将始终优先于第一个声明。因为<code>.blue-text</code>被声明为第二个,所以它会覆盖<code>.pink-text</code>的属性</section>

## Tests
|
|||
|
<section id='tests'>
|
|||
|
|
|||
|
```yml
|
|||
|
tests:
|
|||
|
- text: 您的<code>h1</code>元素应该具有<code>pink-text</code>类。
|
|||
|
testString: 'assert($("h1").hasClass("pink-text"), "Your <code>h1</code> element should have the class <code>pink-text</code>.");'
|
|||
|
- text: 你的<code>h1</code>元素应该有<code>blue-text</code> 。
|
|||
|
testString: 'assert($("h1").hasClass("blue-text"), "Your <code>h1</code> element should have the class <code>blue-text</code>.");'
|
|||
|
- text: <code>blue-text</code>和<code>pink-text</code>都应属于同一个<code>h1</code>元素。
|
|||
|
testString: 'assert($(".pink-text").hasClass("blue-text"), "Both <code>blue-text</code> and <code>pink-text</code> should belong to the same <code>h1</code> element.");'
|
|||
|
- text: 你的<code>h1</code>元素应该是蓝色的。
|
|||
|
testString: 'assert($("h1").css("color") === "rgb(0, 0, 255)", "Your <code>h1</code> element should be blue.");'
|
|||
