有没有办法像我的例子一样选中/取消选中一个圆形按钮？

<input type="checkbox" id="circle-btn">
<label for="circle-btn" class="circle"></label>

.circle {
  display: inline-block;
  width: 20px;
  height: 20px;
  border-radius: 50%;
  border: 2px solid #000;
  cursor: pointer;
}

.circle::after {
  content: "";
  display: block;
  width: 12px;
  height: 12px;
  margin: 3px;
  border-radius: 50%;
  background-color: #000;
  opacity: 0;
}

input[type="checkbox"]:checked + .circle::after {
  opacity: 1;
}
