## Description
|
|||
|
|
<section id="description">到目前为止，挑战中的所有属性都适用于Flex容器（flex项的父级）。但是，flex项有几个有用的属性。第一个是<code>flex-shrink</code>属性。当它被使用时，如果柔性容器太小，它允许物品收缩。当父容器的宽度小于其中所有flex项的组合宽度时，项会收缩。 <code>flex-shrink</code>属性将数字作为值。数字越大，与容器中的其他项目相比，它将收缩得越多。例如，如果一个项目的<code>flex-shrink</code>值为1而另一个项目的<code>flex-shrink</code>值为3，则值为3的项目将缩小为另一个项目的三倍。 </section>
