学到jQuery 遇到这个例子实现完成觉得没啥特效不好看人家原来是有效果的，做一半怎么能行，（结果还是做一半 只是吧动画加上了）。
=============================
首先遇到几个问题总结一下
1.想用原来的float：left 但是需要用动画 所以需要定位position 结果不能一起用，只好全换了，在尝试的的时候试了一下inline-block（理解不透彻犯了傻），结果肯定是没好用，
2. 然而我发现inline-block会识别 回车也就是两个<li>/*这里的回车*/<li>解决办法很多 我觉得最好的是 font-size：0这个效果最好。
3.暂时想不起来了当时问题挺多的，现在才想起来总结。。。
======================================================
好吧效果就是这样 可以试一试我把代码贴再下面 就是判断整个ul在上一条的左边还是右边 然后 相应的remove 相应个数<li>，根据删除后的li确定 创建新的ul 长度
