移动端 单页有时候 制作只用到简单的css3动画即可，我们简单封装一下，没必要引入zepto框架。
var leftsbox=document.getElementById("leftsbox"); var boxdiv=leftsbox.getElementsByTagName("div"); leftsbox.onclick=function(){ for(var i=0;i<boxdiv.length;i++){ var that=boxdiv[i]; transform(that,{ translate3d:'220px,10px,0',left:'1em',opacity:0.2,perspective:'400px', rotateY:'30deg'},800,'cubic-bezier(0.15, 0.5, 0.25, 1.0)',function(){ this.innerHTML='结束回调'+this.innerHTML; },100*i); } //for
