`<basic-shape>`

css

inset( <shape-arg>{1,4} [round <border-radius>]? )
circle( [<shape-radius>]? [at <position>]? )
ellipse( [<shape-radius>{2}]? [at <position>]? )
polygon( [<fill-rule>,]? [<shape-arg> <shape-arg>]# )
path( [<fill-rule>,]? <string>)

<shape-arg> = <length> | <percentage>
<shape-radius> = <length> | <percentage> | closest-side | farthest-side

Example

<basic-shape> 是支持 transition 的，但需要为同一种形状

元素被 clip-path 裁剪的部分不再触发鼠标事件，而是触发被暴露元素的鼠标事件
