<p> Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five www.codefans.net centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. </p>

zjsj_31212014-04-09挺好的，修改一下可用- ws9828679512013-01-23效果还行，可以借鉴一下
- qq_368386922018-01-05草！狗屁啊！下载下来404错误！浪费78元！
heero_rei2013-07-26效果不错，可以作为一种放大缩小效果的参考，自己实现比较麻烦
