flex-grow

示例

允许项目扩展

使用 grow 允许 flex 项目扩展以填充可用空间：

<div class="flex ...">  <div class="size-14 flex-none ...">01</div>  <div class="size-14 grow ...">02</div>  <div class="size-14 flex-none ...">03</div></div>

基于比例因子扩展项目

使用 grow-<number> 工具类（如 grow-3）让弹性项目根据其扩展因子按比例增长，使它们能够相对于彼此填充可用空间：

<div class="flex ...">  <div class="size-14 grow-3 ...">01</div>  <div class="size-14 grow-7 ...">02</div>  <div class="size-14 grow-3 ...">03</div></div>

防止元素扩展

使用 grow-0 阻止弹性项目扩展：

<div class="flex ...">  <div class="size-14 grow ...">01</div>  <div class="size-14 grow-0 ...">02</div>  <div class="size-14 grow ...">03</div></div>

使用自定义值

Use the grow-[<value>] syntax to set the 弹性扩展因子 based on a completely custom value:

<div class="grow-[25vw] ...">  <!-- ... --></div>

For CSS variables, you can also use the grow-(<custom-property>) syntax:

<div class="grow-(--my-grow) ...">  <!-- ... --></div>

This is just a shorthand for grow-[var(<custom-property>)] that adds the var() function for you automatically.

响应式设计

Prefix a flex-grow utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="grow md:grow-0 ...">  <!-- ... --></div>
