ima上的svg剪辑路径(帮手：clip-path-generator) ge和一个没有剪辑路径的blury克隆，都在一个容器内。添加了低透明度的彩色图层，让高光更清晰。 - jsfiddle -

ps.1：在此剪辑路径生成器中，您可以单击并拖动桌面中的图片到画布中。您可以在网络上轻松找到更多剪辑路径生成器，如this one。

ps.2：您可以在图形软件(如Inkscape或Adobe Illustrator)上构建svg图形。

简化版本的它，用一个单一的形象，不带过滤器，无夹路径，使用内置的Adobe Illustrator的坚实SVG形状：

.container {

position: relative;

}

svg {

position: absolute;

top: 0;

left: 0;

}

polygon {

cursor: pointer;

opacity: 0.6;

fill: green;

}

polygon:hover {

opacity: 0.8;

fill: red;

}
