## Description
|
|||
|
<section id="description">让我们再试一次,但这次有<code>margin</code> 。不是单独指定元素的<code>margin-top</code> , <code>margin-right</code> , <code>margin-bottom</code>和<code>margin-left</code>属性,而是可以在一行中指定它们,如下所示: <code>margin: 10px 20px 10px 20px;</code>这四个值的工作方式类似于时钟:top,right,bottom,left,并且将产生与使用边特定边距指令完全相同的结果。 </section>
|
|||
|
|
|||
|
## Instructions
|
|||
|
<section id="instructions">使用<code>Clockwise Notation</code>为<code>blue-box</code>的元素在其顶部和左侧提供<code>40px</code>的边距,但在其底部和右侧仅为<code>20px</code> 。 </section>
|
|||
