变换
transform-origin
用于指定元素变换的原点的工具类。
| Class | 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
基本示例
使用 origin-top 和 origin-bottom-left 等工具类来设置元素的变换原点：
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
Use the origin-[<value>] syntax to set the 变换原点 based on a completely custom value:
<img class="origin-[33%_75%] ..." src="/img/mountains.jpg" />For CSS variables, you can also use the origin-(<custom-property>) syntax:
<img class="origin-(--my-transform-origin) ..." src="/img/mountains.jpg" />This is just a shorthand for origin-[var(<custom-property>)] that adds the var() function for you automatically.
响应式设计
Prefix a transform-origin utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<img class="origin-center md:origin-top ..." src="/img/mountains.jpg" />Learn more about using variants in the variants documentation.
