checkbox制作开关样式

如下是学习心得，如何制作一个开关样式。

.hbk-switch{
  display: inline-block;
  vertical-align: top;
  -webkit-touch-callout: none;
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
.hbk-switch .hbk-helper{
  display: inline-block;
  position: relative; 
  width: 40px;
  height: 16px;
  border-radius: 8px;
  background: rgba(0, 0, 0, 0.26);
  transition: background 0.28s cubic-bezier(0.4, 0, 0.2, 1);
  vertical-align: middle;
  cursor: pointer;
}
.hbk-switch .hbk-helper:before{
  content: '';
  position: absolute;
  top: -4px;
  left: -4px;
  width: 24px;
  height: 24px;
  background: #fafafa;
  box-shadow: 0 2px 8px rgba(0, 0, 0, 0.28);
  border-radius: 50%;
  webkit-transition: left 0.28s cubic-bezier(0.4, 0, 0.2, 1), background 0.28s cubic-bezier(0.4, 0, 0.2, 1), box-shadow 0.28s cubic-bezier(0.4, 0, 0.2, 1);
  transition: left 0.28s cubic-bezier(0.4, 0, 0.2, 1), background 0.28s cubic-bezier(0.4, 0, 0.2, 1), box-shadow 0.28s cubic-bezier(0.4, 0, 0.2, 1);
}
.hbk-switch input {
  position: absolute;
  z-index: 1;
  width: 46px;
  margin: 0 0 0 -4px;
  height: 24px;
  opacity: 0;
  filter: alpha(opacity=0);
  cursor: pointer;
}

.hbk-switch input:checked + .hbk-helper:before {
  left: 20px;
}

前端放到一个ul标签里

效果图如下：
