最大高度

示例

基本示例

使用 max-h-<number> 工具类，如 max-h-24 和 max-h-64，将元素设置为基于间距尺度的固定最大高度：

<div class="h-96 ...">
  <div class="h-full max-h-80 ...">max-h-80</div>
  <div class="h-full max-h-64 ...">max-h-64</div>
  <div class="h-full max-h-48 ...">max-h-48</div>
  <div class="h-full max-h-40 ...">max-h-40</div>
  <div class="h-full max-h-32 ...">max-h-32</div>
  <div class="h-full max-h-24 ...">max-h-24</div>
</div>

使用百分比

使用 max-h-full 或 max-h-<fraction> 工具类，如 max-h-1/2 和 max-h-2/5 为元素提供基于百分比的最大高度：

<div class="h-96 ...">
  <div class="h-full max-h-9/10 ...">max-h-9/10</div>
  <div class="h-full max-h-3/4 ...">max-h-3/4</div>
  <div class="h-full max-h-1/2 ...">max-h-1/2</div>
  <div class="h-full max-h-1/4 ...">max-h-1/4</div>
  <div class="h-full max-h-full ...">max-h-full</div>
</div>

使用自定义值

Use the max-h-[<value>] syntax to set the 最大高度 based on a completely custom value:

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

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

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

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

响应式设计

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

<div class="h-48 max-h-full md:max-h-screen ...">
  <!-- ... -->
</div>

Learn more about using variants in the variants documentation.

自定义主题

The max-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.
