变形 (Transforms)
transform-origin
用于指定元素变形原点的实用工具。(Utilities for specifying the origin for an element's transformations.)
| 类名 (Class) | 样式 (Styles) |
|---|---|
origin-center | transform-origin: center; |
origin-top | transform-origin: top; |
origin-top-right | transform-origin: top right; |
origin-right | transform-origin: right; |
origin-bottom-right | transform-origin: bottom right; |
origin-bottom | transform-origin: bottom; |
origin-bottom-left | transform-origin: bottom left; |
origin-left | transform-origin: left; |
origin-top-left | transform-origin: top left; |
origin-(<custom-property>) | transform-origin: var(<custom-property>); |
origin-[<value>] | transform-origin: <value>; |
示例 (Examples)
基本示例 (Basic example)
使用类似 origin-top 和 origin-bottom-left 这样的工具类来设置元素的变形原点 (Use utilities like origin-top and origin-bottom-left to set an element's transform origin)
origin-center
origin-top-left
origin-bottom
<img class="origin-center rotate-45 ..." src="/img/mountains.jpg" /><img class="origin-top-left rotate-12 ..." src="/img/mountains.jpg" /><img class="origin-bottom -rotate-12 ..." src="/img/mountains.jpg" />使用自定义值 (Using a custom value)
使用 origin-[<value>] 语法 (syntax) 来设置变形原点 (transform origin)基于完全自定义的值 (based on a completely custom value)
<img class="origin-[33%_75%] ..." src="/img/mountains.jpg" />对于 CSS 变量，您也可以使用 (For CSS variables, you can also use the) origin-(<custom-property>) 语法 (syntax)
<img class="origin-(--my-transform-origin) ..." src="/img/mountains.jpg" />这只是 (This is just a shorthand for) origin-[var(<custom-property>)] 的简写，它会自动为您添加 var() 函数。(that adds the var() function for you automatically.)
响应式设计 (Responsive design)
前缀 (Prefix)a transform-origin 实用工具 (utility) 带有断点变体，如 md:，仅在以下情况下应用该实用工具 (with a breakpoint variant like md: to only apply the utility at)中等 (medium) 屏幕尺寸及以上 (screen sizes and above)
<img class="origin-center md:origin-top ..." src="/img/mountains.jpg" />了解更多关于在变体文档中使用变体的信息。(Learn more about using variants in the variants documentation.)
