高度

​基本用法

¥Basic usage

​固定高度

¥Fixed heights

使用 h-px、h-1 和 h-64 等工具将元素设置为固定高度。

¥Use utilities like h-px, h-1, and h-64 to set an element to a fixed height.

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

​全高

¥Full height

使用 h-full 将元素的高度设置为其父元素的 100%，只要父元素具有已定义的高度。

¥Use h-full to set an element’s height to 100% of its parent, as long as the parent has a defined height.

<div class="h-48">
  <div class="h-full ...">
    <!-- This element will have a height of `12rem` (h-48) -->
  </div>
</div>

​视口高度

¥Viewport height

使用 h-screen 使元素跨越视口的整个高度。

¥Use h-screen to make an element span the entire height of the viewport.

<div class="h-screen">
  <!-- ... -->
</div>

​动态视口高度

¥Dynamic viewport height

使用 h-dvh 使元素跨越视口的整个高度，视口的高度会随着浏览器 UI 的扩展或收缩而变化。

¥Use h-dvh to make an element span the entire height of the viewport, which changes as the browser UI expands or contracts.

<div class="h-dvh">
  <!-- ... -->
</div>

​大视口高度

¥Large viewport height

使用 h-lvh 将元素的高度设置为视口的最大可能高度。这与 100vh 的行为相同。

¥Use h-lvh to set an element’s height to the largest possible height of the viewport. This behaves the same as 100vh.

<div class="h-lvh">
  <!-- ... -->
</div>

​小视口高度

¥Small viewport height

使用 h-svh 将元素的高度设置为视口的最小可能高度。

¥Use h-svh to set an element’s height to the smallest possible height of the viewport.

<div class="h-svh">
  <!-- ... -->
</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:h-full to only apply the h-full utility on hover.

<div class="h-8 hover:h-full">
  <!-- ... -->
</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:h-full to apply the h-full utility at only medium screen sizes and above.

<div class="h-8 md:h-full">
  <!-- ... -->
</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 的身高比例是 默认间距比例 以及一些特定于身高的附加值的组合。

¥By default, Tailwind’s 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.

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

要单独自定义高度，请使用 tailwind.config.js 文件的 theme.height 部分。

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

module.exports = {
  theme: {
    extend: {
      height: {
        '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 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="h-[32rem]">
  <!-- ... -->
</div>

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