| 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>。
 | ||
| </section>
 | ||
| 
 | ||
| ## Tests
 | ||
| <section id='tests'>
 | ||
| 
 | ||
| ```yml
 | ||
| tests:

|   - text: <code>#box-1</code>元素应有<code>align-self</code>属性,其值应为 <code>center</code>。
 | ||
|     testString: assert($('#box-1').css('align-self') == 'center');
