title: 使用 flex-grow 属性扩展项目
|
||
---
|
||
|
||
## Description
|
||
<section id='description'>
|
||
与<code>flex-shrink</code>相对的是<code>flex-grow</code>。你应该还记得，<code>flex-shrink</code>会在容器太小时对元素作出调整。相应地，<code>flex-grow</code>会在容器太大时对元素作出调整。
|
||
例子与上一个挑战相似，如果一个项目的<code>flex-grow</code>属性值为 <code>1</code>，另一个项目的<code>flex-grow</code>属性值为 <code>3</code>，那么后者会较前者扩大 3 倍。
