Transform Origin

Utilities for specifying the origin for an element's transformations.

Default class reference

Class
屬性
origin-centertransform-origin: center;
origin-toptransform-origin: top;
origin-top-righttransform-origin: top right;
origin-righttransform-origin: right;
origin-bottom-righttransform-origin: bottom right;
origin-bottomtransform-origin: bottom;
origin-bottom-lefttransform-origin: bottom left;
origin-lefttransform-origin: left;
origin-top-lefttransform-origin: top left;

Usage

Specify an element’s transform origin using the origin-{keyword} utilities.

<img class="origin-center transform rotate-45 ...">
<img class="origin-top-left transform rotate-45 ...">
<img class="origin-bottom-right transform rotate-45 ...">
<img class="origin-left transform rotate-45 ...">

Responsive

To control the transform-origin of an element at a specific breakpoint, add a {screen}: prefix to any existing transform-origin utility. For example, use md:origin-top to apply the origin-top utility at only medium screen sizes and above.

<img class="origin-center md:origin-top ...">

Customizing

Origin values

By default, Tailwind provides transform-origin utilities for all of the built-in browser keyword options. You change, add, or remove these by customizing the transformOrigin section of your Tailwind theme config.

  // tailwind.config.js
  module.exports = {
    theme: {
      extend: {
        transformOrigin: {
+         '24': '6rem',
+         '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 transform-origin 變化模式 (variants) 會產生。

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

Disabling

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

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