稍微改一下，就实现了你说的功能，主要是阻止浏览器的body默认事件，不然在移动页面的时候会屏蔽掉相关的 js 事件，再自定义start、move、end几个方法，如下：

<style type="text/css">
*{margin: 0;}

#a{

}
#b{
background: #ddd;
line-height: 200px;
height: 200px;
position: absolute;
width: 100%;
text-align: center;
left: 0;
top: 0;
}
#b.ease{
-webkit-transition: all 0.3s ease 0s;
-moz-transition: all 0.3s ease 0s;
-ms-transition: all 0.3s ease 0s;
-o-transition: all 0.3s ease 0s;

}
#c{

border-top: 1px solid #999;
border-bottom: 1px solid #999;

}
#d{

height: 40px;
position: relative;
overflow: hidden;
}
#e{
float: left;
}
</style>
