最小宽度

示例

基本示例

使用 min-w-<number> 工具类，如 min-w-24 和 min-w-64，根据间距比例设置元素的固定最小宽度：

<div class="w-20 ...">
  <div class="min-w-80 ...">min-w-80</div>
  <div class="min-w-64 ...">min-w-64</div>
  <div class="min-w-48 ...">min-w-48</div>
  <div class="min-w-40 ...">min-w-40</div>
  <div class="min-w-32 ...">min-w-32</div>
  <div class="min-w-24 ...">min-w-24</div>
</div>

使用百分比

使用 min-w-full 或 min-w-<fraction> 工具类，如 min-w-1/2 和 min-w-2/5，给元素提供基于百分比的最小宽度：

<div class="flex ...">
  <div class="min-w-3/4 ...">min-w-3/4</div>
  <div class="w-full ...">w-full</div>
</div>

使用容器比例

使用工具类，如 min-w-sm 和 min-w-xl，根据容器比例设置元素的固定最小宽度：

<div class="w-40 ...">
  <div class="min-w-lg ...">min-w-lg</div>
  <div class="min-w-md ...">min-w-md</div>
  <div class="min-w-sm ...">min-w-sm</div>
  <div class="min-w-xs ...">min-w-xs</div>
  <div class="min-w-2xs ...">min-w-2xs</div>
  <div class="min-w-3xs ...">min-w-3xs</div>
</div>

使用自定义值

Use the min-w-[<value>] syntax to set the 最小宽度 based on a completely custom value:

<div class="min-w-[220px] ...">
  <!-- ... -->
</div>

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

<div class="min-w-(--my-min-width) ...">
  <!-- ... -->
</div>

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

响应式设计

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

<div class="w-24 min-w-full md:min-w-0 ...">
  <!-- ... -->
</div>

Learn more about using variants in the variants documentation.

自定义你的主题

The min-w-<number> utilities are driven by the --spacing theme variable, which can be customized in your own theme:

@theme {
  --spacing: 1px; 
}
