css3はスイッチコンポーネントスイッチを実装します

<input class=&#39;switch-component&#39; type=&#39;checkbox&#39;>

// switch组件
.switch-component {
  position: relative;
  width: 60px;
  height: 30px;
  background-color: #dadada;
  border-radius: 30px;
  border: none;
  outline: none;
  -webkit-appearance: none;
  transition: all .2s ease;
}

// 按钮
switch-component::after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 50%;
  height: 100%;
  background-color: #fff;
  border-radius: 50%;
  transition: all .2s ease;
 }

// checked状态时，背景颜色改变
.switch-component:checked {
  background-color: #86c0fa;
}

// checked状态时，按钮位置改变
.switch-component:checked::after {
  left: 50%;
 }
