前面的话

　　CSS借鉴了SVG裁剪的概念，设置了clip-path样式，本文将详细介绍路径裁剪clip-path

 

概述

　　clip-path属性可以防止部分元素通过定义的剪切区域来显示，仅通过显示的特殊区域。剪切区域是被URL定义的路径代替行内或者外部svg，或者定义路线的方法

　　[注意]IE浏览器不支持，且低版本webkit内核浏览器需要添加-webkit-前缀

【clip-path】

　　值: <clip-source> | [ <basic-shape> || <geometry-box> ] | none

　　<clip-source>: url()

　　<basic-shape>:  inset() | circle() | ellipse() | polygon() 

　　<geometry-box>: fill-box | stroke-box | view-box | margin-box | border-box | padding-box | content-box 

　　初始值: none

　　应用于: 所有元素

　　继承性: 无
