如何在左侧制作外厚内薄的双边框

Question

我想在左侧制作双边框，只有粗轮廓（外）和细轮廓（内）。我怎样才能做到？

Answer 1

我想这就是你要找的..

.border1{
  width:100px;
  height:100px;
  border-left: 10px solid #ccc;
  }
.border2{
 width: 100px;
 height: 100px;
 display: block;
 margin-left: 15px;
 border-left: 3px solid #ccc;
  }

<div class="border1">
  <div class="border2"></div>
</div>

检查一下，如果您还需要其他任何东西，请告诉我..
