data--，不然看不出效果，如下代码所示

2、data-[]中的offer可以很大，也可以很小，它的值大小也是能达到某种效果的重点哦！

html, body {width:100%;height:100%;padding:0;margin:0;overflow-x:hidden;}/*.skrollable重要，它能达到意想不到的效果，它由js加载*/.skrollable {position:fixed;z-index:100;}#skrollr-body {height:100%;overflow:visible;position:relative;z-index: 101;}#center {background:#f9f9f9;background:rgba(240,240,240,.7);width:90%;padding:1em;margin:1em auto;border:1px solid #bbb;}#bg1, #bg2, #bg3 {z-index:50;top:0;left:0;width:100%;height:100%;background:url(images/bubbles.png) repeat 0 0;}#bg2 {z-index:49;background-image:url(images/bubbles2.png);}#bg3 {z-index:48;background-image:url(images/bubbles3.png);}
