Default class reference

Class
屬性
min-h-0min-height: 0px;
min-h-fullmin-height: 100%;
min-h-screenmin-height: 100vh;

Usage

Set the minimum height of an element using the min-h-0, min-h-full, or min-h-screen utilities.

.min-h-full
<div class="h-48 ...">
  <div class="h-24 min-h-full ...">
    .min-h-full
  </div>
</div>

Responsive

To control the min-height of an element at a specific breakpoint, add a {screen}: prefix to any existing min-height utility.

<div class="h-48 ...">
  <div class="h-24 min-h-0 md:min-h-full ...">
    <!-- ... -->
  </div>
</div>

Customizing

Min-height scale

Customize Tailwind’s default min-height scale in the theme.minHeight section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
      minHeight: {
+       '0': '0',
+       '1/4': '25%',
+       '1/2': '50%',
+       '3/4': '75%',
+       'full': '100%',
      }
    }
  }

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

Variants

默認情況下, 只有 響應式 的 min-height 變化模式 (variants) 會產生。

tailwind.config.jsvariants 區塊中變更 minHeight 屬性來決定有哪些變化模式會生成。

舉個例子來說,這個設定將會生成 響應式 和 hover 的變化模式。

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       minHeight: ['responsive', 'hover'],
      }
    }
  }

Disabling

如果你不打算在專案中使用 min-height 功能,可以在你的設定檔裡的 corePlugins 屬性中將 minHeight 設定為 false 來停用功能:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     minHeight: false,
    }
  }
