Max-Width

Usage

Set the maximum width of an element using the max-w-{size} utilities.

Reading width

The max-w-prose utility gives an element a max-width optimized for readability and adapts based on the font size.

Constraining to your breakpoints

The max-w-screen-{breakpoint} classes can be used to give an element a max-width matching a specific breakpoint. These values are automatically derived from the theme.screens section of your tailwind.config.js file.

<div class="max-w-screen-2xl">
  <!-- ... -->
</div>

Responsive

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

<div class="max-w-sm md:max-w-lg ...">
  <!-- ... -->
</div>

Customizing

Max-Width Scale

Customize Tailwind’s default max-width scale for the max-w-* classes in the theme.maxWidth section of your tailwind.config.js file.

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

The max-w-screen-* classes are derived from the theme.screens section of your tailwind.config.js file.

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

Variants

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

在 tailwind.config.js 的 variants 區塊中變更 maxWidth 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: {
        // ...
+       maxWidth: ['responsive', 'hover'],
      }
    }
  }

Disabling

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

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