								## 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>

								 | 
							
								<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>
