localeTitle: 使用align-self属性

## Description
<section id="description"> flex项的最终属性是<code>align-self</code> 。此属性允许您单独调整每个项目的对齐方式，而不是一次性设置它们。这很有用，因为使用CSS属性<code>float</code> ， <code>clear</code>和<code>vertical-align</code>其他常用调整技术对flex项不起作用。 <code>align-self</code>接受与<code>align-items</code>相同的值，并将覆盖<code>align-items</code>属性设置的任何值。 </section>

## Instructions
<section id="instructions">将CSS属性<code>align-self</code>添加到<code>#box-1</code>和<code>#box-2</code> 。给<code>#box-1</code>一个中心值，给<code>#box-2</code>一个flex-end值。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: '<code>#box-1</code>元素应将<code>align-self</code>属性设置为center的值。'
    testString: 'assert($("#box-1").css("align-self") == "center", "The <code>#box-1</code> element should have the <code>align-self</code> property set to a value of center.");'
  - text: '<code>#box-2</code>元素应该将<code>align-self</code>属性设置为flex-end的值。'
    testString: 'assert($("#box-2").css("align-self") == "flex-end", "The <code>#box-2</code> element should have the <code>align-self</code> property set to a value of flex-end.");'
