最小高度

示例

基本示例

使用 min-h-<number> 工具类，如 min-h-24 和 min-h-64，将元素设置为基于间距比例的固定最小高度：

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

使用百分比

使用 min-h-full 或者 min-h-<fraction> 工具类，如 min-h-1/2 和 min-h-2/5 来设置元素的基于百分比的最小高度：

<div class="min-h-full ...">min-h-full</div>
<div class="min-h-9/10 ...">min-h-9/10</div>
<div class="min-h-3/4 ...">min-h-3/4</div>
<div class="min-h-1/2 ...">min-h-1/2</div>
<div class="min-h-1/3 ...">min-h-1/3</div>

使用自定义值

Use the min-h-[<value>] syntax to set the 最小高度 based on a completely custom value:

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

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

<div class="min-h-(--my-min-height) ...">
  <!-- ... -->
</div>

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

响应式设计

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

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

Learn more about using variants in the variants documentation.

自定义你的主题

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

@theme {
  --spacing: 1px; 
}

Learn more about customizing the spacing scale in the theme variable documentation.
