## Description
|
||
<section id="description">不是单独指定元素的<code>padding-top</code> ， <code>padding-right</code> ， <code>padding-bottom</code>和<code>padding-left</code>属性，而是可以在一行中指定它们，如下所示： <code>padding: 10px 20px 10px 20px;</code>这四个值的工作方式类似于时钟：顶部，右侧，底部，左侧，并且将产生与使用侧面特定填充指令完全相同的结果。 </section>
|
||
|
||
## Instructions
|
||
<section id="instructions">使用顺时针符号为“.blue-box”类在其顶部和左侧提供<code>40px</code>的<code>padding</code> ，但在其底部和右侧仅为<code>20px</code> 。 </section>
|
||
|
||
## Tests
|
||
<section id='tests'>
|
||
|
||
```yml
|
||
tests:
|
||
- text: 你的<code>blue-box</code>类应该给出<code>40px</code> <code>padding</code>元素的顶部。
|
||
testString: 'assert($(".blue-box").css("padding-top") === "40px", "Your <code>blue-box</code> class should give the top of elements <code>40px</code> of <code>padding</code>.");'
|
||
- text: 你的<code>blue-box</code>类应该给出<code>20px</code> <code>padding</code>元素的权利。
|
||
testString: 'assert($(".blue-box").css("padding-right") === "20px", "Your <code>blue-box</code> class should give the right of elements <code>20px</code> of <code>padding</code>.");'
|
||
- text: 你的<code>blue-box</code>类应该给元素的底部提供<code>20px</code>的<code>padding</code> 。
|
||
testString: 'assert($(".blue-box").css("padding-bottom") === "20px", "Your <code>blue-box</code> class should give the bottom of elements <code>20px</code> of <code>padding</code>.");'
|
||
- text: 你的<code>blue-box</code>类应该给元素左边<code>padding</code> <code>40px</code> 。
|
||
testString: 'assert($(".blue-box").css("padding-left") === "40px", "Your <code>blue-box</code> class should give the left of elements <code>40px</code> of <code>padding</code>.");'
|
||
- text: 您应该使用顺时针符号来设置<code>blue-box</code>类的填充。
|
||
testString: 'assert(!/padding-top|padding-right|padding-bottom|padding-left/.test(code), "You should use the clockwise notation to set the padding of <code>blue-box</code> class.");'
