## Description
|
||
<section id='description'>
|
||
这节会使用一种不同的挑战方式来学习一下如何使用 CSS 更灵活地布局元素。首先通过一个挑战来理解原理，然后通过操作一个简单的推文组件来应用“弹性盒子”（flexbox）。
|
||
只要在一个元素的 CSS 中添加<code>display: flex;</code>，就可以使用其它 flex 属性来构建响应式页面了。
|
||

|
||
|
||
## Instructions
|
||
<section id='instructions'>
|
||
为<code>#box-container</code>添加<code>display</code>属性，设置其值为 <code>flex</code>。
