通过使用css3实现让元素椭圆运动。而不是圆形运动。

效果1：http://sandbox.runjs.cn/show/ignefell

效果2：http://runjs.cn/code/w2wxjyeo

代码如下：

<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"><meta name="viewport" content="initial-scale=1.0,maximum-scale=1.0,user-scalable=no"><link rel="stylesheet" href="css/base.css"></head><body><style>html{-ms-text-size-adjust:100%;-webkit-text-size-adjust:100%;}
ul,li,div,p,body{margin:0;padding:0;text-align:left;}
body, html {background:#001424;text-align: left;height: 100%;width: 100%;font-family: "Microsoft YaHei","Helvetica Neue",Arial, HelveticaNeue, "Helvetica-Neue", Helvetica, "BBAlpha Sans", sans-serif;font-size:62.5%;font-weight: normal;}
