波浪边框css一圈

Question

有没有一种方法可以使波浪背景变成圆圈。

我可以轻松获得圆形，但不确定如何才能像给定图片中那样获得边框。

<div class="circle-wave">

</div>

.circle-wave {
 cursor: pointer;
 height: 50px;
 width: 50px;
 border-radius: 50%;
}

Answer 1

根据先前的答案（我在其中创建了类似“ zig-zag-border-for- acircle” 的圆），您可以进行一些调整以具有此布局。基本上，我向SVG元素添加了笔触，然后添加了径向渐变以覆盖不需要的部分。顺便说一句，这是一个没有透明度的解决方案。

.zigzag {
   width:256px;
   height:256px;
   background:
    radial-gradient(#fff 60%,transparent 61%),

    background-size:100% 100%;

    display:inline-block;
}

<div class="zigzag">
</div>
<div class="zigzag" style="width:100px;height:100px;">
</div>
<div class="zigzag" style="width:50px;height:50px;">
</div>

如果要透明，可以修改SVG元素，使其仅在顶部和底部保持两个三角形，如下所示：

svg {
  stroke: red;
  stroke-width: 3px;
  fill: transparent;
  border: 1px solid;
}
svg polygon:first-child {
  stroke-dasharray: 45, 35;
}
svg polygon:last-child {
  stroke-dasharray: 45, 35;
  stroke-dashoffset: -32;
}

<svg xmlns='http://www.w3.org/2000/svg' viewBox='-97 -3 256 262' width='256'> 
<polygon points='48,16 32,0 16,16' />
<polygon points='48,240 16,240 32,256' />
</svg>

然后只需将其集成到后台即可：

.zigzag {
   width:256px;
   height:256px;
   background:
    url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' viewBox='-97 -3 256 262' width='256' stroke-dasharray='45, 35' stroke='red' stroke-width='3' fill='transparent'><polygon points='48,16 32,0 16,16' /><polygon points='48,240 16,240 32,256' stroke-dashoffset='-32' /></svg>"),
