<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: ;
}
</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>
