我将这个CSS用于带有一种边框颜色的圆圈:



.circle {
  border: 6px solid #ffd511;
  border-radius: 30px;
  -moz-border-radius: 30px;
  -webkit-border-radius: 30px;
  -khtml-border-radius: 30px;
  width: 30px;
  height: 18px;
  line-height: 20px;
  padding: 12px 6px;
  text-align: center;
}

<div class="circle">17</div>
&#13;
&#13;
&#13;

看起来像这样:

circle with one border color

如何将CSS更改为三种边框颜色 - 与时钟一样:

  • 从0到4色#1
  • 从4到8色#2
  • 从8到12颜色#3

我确信,这可能是元素<canvas>,但我没有成功。

您可以使用inline svg实现圆形边框分为3个部分

以下是一个例子:

svg{width:30%;height:auto;}
<svg viewbox="0 0 10 10">
  <defs>
    <circle id="circle" cx="5" cy="5" r="4" stroke-width="0.5" fill="transparent" />
  </defs>
  <use xlink:href="#circle" stroke="pink" stroke-dasharray="0,2.09,8.38,30" />
  <use xlink:href="#circle" stroke="green" stroke-dasharray="0,10.47,8.38,30" />
  <use xlink:href="#circle" stroke="orange" stroke-dasharray="2.09,16.75,6.3" />
</svg>

修改

要在圈子中添加文字,您可以使用svg text element

svg{width:30%;height:auto;}
<svg viewbox="0 0 10 10">
  <defs>
    <circle id="circle" cx="5" cy="5" r="4" stroke-width="0.5" fill="transparent" />
  </defs>
  <use xlink:href="#circle" stroke="pink" stroke-dasharray="0,2.09,8.38,30" />
  <use xlink:href="#circle" stroke="green" stroke-dasharray="0,10.47,8.38,30" />
  <use xlink:href="#circle" stroke="orange" stroke-dasharray="2.09,16.75,6.3" />
  <text x="5" y="6.5" text-anchor="middle" font-size="5">17</text>
</svg>
