Grow

Use flex-grow to allow a flex item to grow to fill any available space:

<div class="flex ...">
  <div class="flex-none w-16 h-16 ...">
    <!-- This item will not grow -->
  </div>
  <div class="flex-grow h-16 ...">
    <!-- This item will grow -->
  </div>
  <div class="flex-none w-16 h-16 ...">
    <!-- This item will not grow -->
  </div>
</div>

Don't grow

Use flex-grow-0 to prevent a flex item from growing:

<div class="flex ...">
  <div class="flex-grow h-16 ...">
    <!-- This item will grow -->
  </div>
  <div class="flex-grow-0 h-16 ...">
    <!-- This item will not grow -->
  </div>
  <div class="flex-grow h-16 ...">
    <!-- This item will grow -->
  </div>
</div>

Responsive

To control how a flex item grows at a specific breakpoint, add a {screen}: prefix to any existing utility class. For example, use md:flex-grow-0 to apply the flex-grow-0 utility at only medium screen sizes and above.

<div class="flex ...">
  <!-- ... -->
  <div class="flex-grow md:flex-grow-0 ...">
    Responsive flex item
  </div>
  <!-- ... -->
</div>

Customizing

Grow Values

By default, Tailwind provides two flex-grow utilities. You change, add, or remove these by editing the theme.flexGrow section of your Tailwind config.

  // tailwind.config.js
  module.exports = {
    theme: {
      flexGrow: {
        '0': 0,
-       DEFAULT: 1,
+       DEFAULT: 2,
+       '1': 1,
      }
    }
  }

Variants

默認情況下, 只有 響應式 的 flex grow 變化模式 (variants) 會產生。

tailwind.config.jsvariants 區塊中變更 flexGrow 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: {
        // ...
+       flexGrow: ['responsive', 'hover'],
      }
    }
  }

Disabling

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

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