变换原点

​基本用法

¥Basic usage

​改变变换原点

¥Changing the transform origin

使用 origin-* 工具指定元素的变换原点。

¥Specify an element’s transform origin using the origin-* utilities.

origin-center

origin-top-left

origin-bottom

<img class="origin-center rotate-45 ...">
<img class="origin-top-left rotate-12 ...">
<img class="origin-bottom -rotate-12 ...">

​有条件地应用

​悬停、聚焦和其他状态

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:origin-top to only apply the origin-top utility on hover.

<div class="origin-center hover:origin-top">
  <!-- ... -->
</div>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:origin-top to apply the origin-top utility at only medium screen sizes and above.

<div class="origin-center md:origin-top">
  <!-- ... -->
</div>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

​使用自定义值

¥Using custom values

​自定义主题

¥Customizing your theme

默认情况下，Tailwind 为所有内置浏览器关键字选项提供 transform-origin 工具。你可以通过编辑 tailwind.config.js 文件中的 theme.transformOrigin 或 theme.extend.transformOrigin 来自定义这些值。

¥By default, Tailwind provides transform-origin utilities for all of the built-in browser keyword options. You can customize these values by editing theme.transformOrigin or theme.extend.transformOrigin in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      transformOrigin: {
        'top-left-1/3-3/4': '33% 75%',
      }
    }
  }
}

在 主题定制 文档中了解有关自定义默认主题的更多信息。

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

​任意值

¥Arbitrary values

If you need to use a one-off transform-origin value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="origin-[33%_75%]">
  <!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
