  <style>
    .ipt {
      display: none;
    }
    .box {
      width: 74px;
      height: 30px;
      line-height: 30px;
      overflow: hidden;
      border: 1px solid #eee;
      border-radius: 4px;
      position: relative;
      cursor: pointer;
    }
    label {display:inline-block;}
    .ipt:checked + .box .switch-btn {
      left: 0;
    }
    .switch-btn {
      position: absolute;
      left: -37px;
      top: 0;
      width: 111px;
      height: 30px;
      transition: all 0.5s;
    }
    .switch-btn span{
      width: 37px;
      height: 30px;
      display: block;
      text-align: center;      
      float: left;
      font-size: 14px;
    }
    .on {
      background: #52B13C;
      color: white;
    }
    .white {
      background: white;
    }
    .off {
      background: #EEEEEE;
    }
  </style>
</head>
<body>
  <p>主要使用label+input来实现改变left的值,下面是核心代码，意思就是<code>选中的input的兄弟节点.box下的.switch-btn元素的left会变成0px(原来是-37px);</code></p>
  <pre>
    .ipt:checked + .box .switch-btn {
      left: 0;
    }
  </pre>
  <p>当然要配合transition来实现</p>
  <p>下面是效果</p>
  <div class="wrap">
    <label>
      <input class="ipt" type="checkbox" name="" value="">
      <div class="box">
        <div class="switch-btn">
          <span class="on">ON</span>
          <span class="white"></span>
          <span class="off">OFF</span>
        </div>
      </div>
    </label>
  </div>
  <p>全部css代码</p>
  <pre>
      .ipt {
        display: none;
      }
      .box {
        width: 74px;
        height: 30px;
        line-height: 30px;
        overflow: hidden;
        border: 1px solid #eee;
        border-radius: 4px;
        position: relative;
        cursor: pointer;
      }
      .ipt:checked + .box .switch-btn {
        left: 0;
      }
      .switch-btn {
        position: absolute;
        left: -37px;
        top: 0;
        width: 111px;
        height: 30px;
        transition: all 0.5s;
      }
      .switch-btn span{
        width: 37px;
        height: 30px;
        display: block;
        text-align: center;      
        float: left;
        font-size: 14px;
      }
      .on {
        background: #52B13C;
        color: white;
      }
      .white {
        background: white;
      }
      .off {
        background: #EEEEEE;
      }
  </pre>
