Description

本节使用交替挑战样式来展示如何使用CSS以灵活的方式定位元素。首先，挑战将解释理论，然后使用简单推文组件的实际挑战将应用flexbox概念。放置CSS属性display: flex;在元素上允许您使用其他flex属性来构建响应式页面。

Instructions

将CSS属性display添加到#box-container并将其值设置为flex。

Tests

tests:
  - text: '<code>#box-container</code>应将<code>display</code>属性设置为flex值。'
    testString: 'assert($("#box-container").css("display") == "flex", "<code>#box-container</code> should have the <code>display</code> property set to a value of flex.");'

Challenge Seed

<style>
  #box-container {
    height: 500px;

  }

  #box-1 {
    background-color: dodgerblue;
    width: 50%;
    height: 50%;

  }

  #box-2 {
    background-color: orangered;
    width: 50%;
    height: 50%;

  }
</style>
<div id="box-container">
  <div id="box-1"></div>
  <div id="box-2"></div>
</div>
