html - 如何创建内部切割的透明圆圈？

Question

我们可以用 css 和 html 创建透明的圆圈吗？我已附上图片以进行说明

.circle {
  width: 150px;
  height: 150px;
  border-radius: 50%;
  border: 1px solid black;
}

<div class="circle"></div>

Answer 1

你可以用:after伪元素来做到这一点

.circle {
  width: 150px;
  height: 150px;
  border-top: 2px solid black;
  border-left: 2px solid black;
  border-right: 2px solid black;
  border-bottom: 2px solid transparent;
  border-radius: 50%;
  position: relative;
  transform: rotate(30deg);
}

.circle:after {
  content: '';
  position: absolute;
  bottom: 0;
  border-radius: 50%;
  height: 10px;
  width: 40px;
  left: 50%;
  transform: translate(-50%, 7%);
  border-bottom: 2px solid black;
  border-top: 2px solid transparent;
  border-left: 2px solid transparent;
  border-right: 2px solid transparent;
}

<div class="circle"></div>
