使用jQuery和CSS3创建一个全屏幕幻灯效果
在今天这篇文章中，我们将介绍来自于tympanus的 一个全屏幻灯特效教程，在这个教程中将介绍如何使用jQuery和CSS3来实现一个全屏的幻灯特效，你将看到每一个幻灯都从水平或者垂直中间断开然后消 失，使用不同的data-attributes属性来定义类型，旋转和角度等幻灯属性，这样我们可以创建非常独特的幻灯效果。
我们将使用到如下的插件：
- jQuery cond by Ben Alman：帮助你使用链式来书写if-then-else语句
- jQuery Transit by Rico Sta. Cruz：帮助你更见简单快捷的使用CSS3动画
