Stretch

Use items-stretch to stretch items to fill the container’s cross axis:

1
2
3
<div class="flex items-stretch ...">
  <div class="py-4">1</div>
  <div class="py-12">2</div>
  <div class="py-8">3</div>
</div>

Start

Use items-start to align items to the start of the container’s cross axis:

1
2
3
<div class="flex items-start ...">
  <div class="h-12">1</div>
  <div class="h-24">2</div>
  <div class="h-16">3</div>
</div>

Center

Use items-center to align items along the center of the container’s cross axis:

1
2
3
<div class="flex items-center ...">
  <div>1</div>
  <div>2</div>
  <div>3</div>
</div>

End

Use items-end to align items to the end of the container’s cross axis:

1
2
3
<div class="flex items-end ...">
  <div>1</div>
  <div>2</div>
  <div>3</div>
</div>

Baseline

Use items-baseline to align items along the container’s cross axis such that all of their baselines align:

1
2
3
<div class="flex items-baseline ...">
  <div class="pt-4 pb-6 ...">1</div>
  <div class="pt-6 pb-10 ...">2</div>
  <div class="pt-8 pb-4 ...">3</div>
</div>

Responsive

To control the alignment of flex items at a specific breakpoint, add a {screen}: prefix to any existing utility class. For example, use md:items-center to apply the items-center utility at only medium screen sizes and above.

<div class="items-stretch md:items-center ...">
  <!-- ... -->
</div>

Customizing

Variants

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

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

Disabling

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

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