Question

我是第一次使用剪辑路径，我需要在此形状中添加边框。任何人都可以向我解释如何做到这一点？

.image-center {
  width: 300px;
  height: 300px;
  margin: 0 auto;
}
.shape {
  width: 300px;
  height: 300px;
  -webkit-clip-path: polygon(15% 0, 70% 0, 100% 50%, 70% 100%, 15% 100%, 0 70%, 20% 50%, 0% 30%);
  clip-path: polygon(15% 0, 70% 0, 100% 50%, 70% 100%, 15% 100%, 0 70%, 20% 50%, 0% 30%);
}
img {
  width: 300px;
  height: 300px;
}

<div class="image-center">
  <div class="shape">
    <img src="http://www.businessadvisorsmd.com/wp-content/uploads/2016/01/masteraccounting-1.jpg" />
  </div>
</div>

您可以使用多个投影滤镜来伪造它。支持不多，但cli路径也不多...

.image-center {
  width: 300px;
  height: 300px;
  margin: 0 auto;
  -webkit-filter: drop-shadow(2px 2px 0px red)
    drop-shadow(2px -2px 0px red)
    drop-shadow(-2px 2px 0px red)
    drop-shadow(-2px -2px 0px red);
  filter: drop-shadow(2px 2px 0px red)
    drop-shadow(2px -2px 0px red)
    drop-shadow(-2px 2px 0px red)
    drop-shadow(-2px -2px 0px red);
}
.shape {
  width: 300px;
  height: 300px;
  -webkit-clip-path: polygon(15% 0, 70% 0, 100% 50%, 70% 100%, 15% 100%, 0 70%, 20% 50%, 0% 30%);
  clip-path: polygon(15% 0, 70% 0, 100% 50%, 70% 100%, 15% 100%, 0 70%, 20% 50%, 0% 30%);
}
img {
  width: 300px;
  height: 300px;
}

<div class="image-center">
  <div class="shape">
    <img src="http://www.businessadvisorsmd.com/wp-content/uploads/2016/01/masteraccounting-1.jpg" />
  </div>
</div>
