基本用法

¥Basic usage

设置最大高度

¥Setting the maximum height

使用 max-h-* 工具设置元素的最大高度。

¥Set the maximum height of an element using max-h-* utilities.

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

有条件地应用

悬停、聚焦和其他状态

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:max-h-screen to only apply the max-h-screen utility on hover.

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

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:max-h-screen to apply the max-h-screen utility at only medium screen sizes and above.

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

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

使用自定义值

¥Using custom values

自定义主题

¥Customizing your theme

默认情况下，Tailwind 的最大高度比例是 默认间距比例 以及一些特定于高度的附加值的组合。

¥By default, Tailwind’s maximum height scale is a combination of the default spacing scale as well as some additional values specific to heights.

你可以通过编辑 tailwind.config.js 文件中的 theme.spacing 或 theme.extend.spacing 来自定义间距比例。

¥You can customize your spacing scale by editing theme.spacing or theme.extend.spacing in your tailwind.config.js file.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      spacing: {
        '128': '32rem',
      }
    }
  }
}

要单独自定义 max-height，请使用 tailwind.config.js 文件的 theme.minHeight 部分。

¥To customize max-height separately, use the theme.minHeight section of your tailwind.config.js file.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      maxHeight: {
        '128': '32rem',
      }
    }
  }
}

在 主题定制 文档中了解有关自定义默认主题的更多信息。

¥Learn more about customizing the default theme in the theme customization documentation.

任意值

¥Arbitrary values

If you need to use a one-off max-height value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

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

Learn more about arbitrary value support in the arbitrary values documentation.
