## Description
<section id="description">所以我们已经证明了id声明覆盖了类声明无论它们在<code>style</code>元素CSS中的声明位置如何。还有其他方法可以覆盖CSS。你还记得内联样式吗 </section>
## Instructions
<section id="instructions">使用<code>inline style</code>尝试使我们的<code>h1</code>元素变白。请记住,在线条样式中如下所示: <code>&lt;h1 style=&quot;color: green;&quot;&gt;</code><code>h1</code>元素上保留<code>blue-text</code><code>pink-text</code>类。 </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: 您的<code>h1</code>元素应具有<code>orange-text</code>的ID。
testString: 'assert($("h1").attr("id") === "orange-text", "Your <code>h1</code> element should have the id of <code>orange-text</code>.");'
- text: 为您的<code>h1</code>元素提供内联样式。
testString: 'assert(document.querySelector("h1[style]"), "Give your <code>h1</code> element an inline style.");'
- text: 你的<code>h1</code>元素应该是白色的。
