localeTitle: 使用 align-self 属性
|
||
---
|

|

## Description
|
||
<section id='description'>
|
||
flex 子项目的最后一个属性是<code>align-self</code>。这个属性允许你调整每个项目自己的对齐方式，而不是一次性设置全部项目。因为<code>float</code>、<code>clear</code>和<code>vertical-align</code>等调整对齐方式的属性都不能应用于 flex 子元素，所以这个属性显得十分有用。
|
||
<code>align-self</code>可设置的值与<code>align-items</code>的一样，并且它会覆盖<code>align-items</code>的值。
|
||
</section>
|
||
|
||
## Instructions
|
||
<section id='instructions'>
|
||
在<code>#box-1</code>和<code>#box-2</code>添加 CSS 属性<code>align-self</code>。<code>#box-1</code>设为 center，<code>#box-2</code>设为 <code>flex-end</code>。

||
