Align Self

Utilities for controlling how an individual flex or grid item is positioned along its container's cross axis.

Default class reference

Class
屬性
self-autoalign-self: auto;
self-startalign-self: flex-start;
self-endalign-self: flex-end;
self-centeralign-self: center;
self-stretchalign-self: stretch;
self-baselinealign-self: baseline;

Auto

Use self-auto to align an item based on the value of the container’s align-items property:

1
2
3
<div class="flex items-stretch ...">
  <div>1</div>
  <div class="self-auto ...">2</div>
  <div>3</div>
</div>

Start

Use self-start to align an item to the start of the container’s cross axis, despite the container’s align-items value:

1
2
3
<div class="flex items-stretch ...">
  <div>1</div>
  <div class="self-start ...">2</div>
  <div>3</div>
</div>

Center

Use self-center to align an item along the center of the container’s cross axis, despite the container’s align-items value:

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

End

Use self-end to align an item to the end of the container’s cross axis, despite the container’s align-items value:

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

Stretch

Use self-stretch to stretch an item to fill the container’s cross axis, despite the container’s align-items value:

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

Responsive

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

<div class="items-stretch ...">
  <div class="self-auto md:self-end ...">
    <!-- ... -->
  </div>
</div>

Customizing

Variants

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

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

Disabling

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

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