| ## Description
 | ||
| <section id="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<code>display: flex;</code>在元素上允许您使用其他flex属性来构建响应式页面。 </section>
 | ||
| 
 | ||
| ## Instructions
 | ||
| <section id="instructions">将CSS属性<code>display</code>添加到<code>#box-container</code>并将其值设置为flex。 </section>
 | ||
| 
 | ||
| ## Tests

| 
 | ||
| ```yml
 | ||
| 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.");'
