## Description
|
||
<section id="description">现在让我们将我们的Cat Photo App放一段时间，了解更多关于样式HTML的信息。您可能已经注意到了这一点，但所有HTML元素基本上都是小矩形。三个重要属性控制每个HTML元素周围的空间： <code>padding</code> ， <code>margin</code>和<code>border</code> 。元素的<code>padding</code>控制元素内容与其<code>border</code>之间的空间量。在这里，我们可以看到蓝色框和红色框嵌套在黄色框中。请注意，红色框具有比蓝色框更多的<code>padding</code> 。当您增加蓝框的<code>padding</code> ，它将增加文本与其周围边框之间的距离（ <code>padding</code> ）。 </section>
|
||
|
||
## Instructions
|
||
<section id="instructions">更改蓝色框的<code>padding</code>以匹配红色框的<code>padding</code> 。 </section>
|
||
|
||
## Tests

|
||
- text: 你的<code>blue-box</code>类应该给出<code>20px</code>的<code>padding</code>元素。

testString: 'assert($(".blue-box").css("padding-top") === "20px", "Your <code>blue-box</code> class should give elements <code>20px</code> of <code>padding</code>.");'
