CSS3构建的3D盒子之导航应用
1.在用css3构建的盒子表面，放上iframe，来加载导航页面。
2.鼠标左键按下移动可旋转盒子，寻找想要的网址。
3.左键单机盒子表面，将全屏现实所点盒子表面的网站[iframe中]，并可浏览，关闭后返回原来状态。
4.PC端，将额外显示2个css3做的旋转盒子[没什么意义]
5.移动端只显示一个导航盒子[模拟器正常，真机无效，留待以后查看，兼容开发有待提高。。。]
注：原本打算排列导航盒子，这样的话导航也变得比较好玩
但是，如果使用iframe来显示网站预览的话，速度太慢，太耗内存
尝试过用html2canvas，但是由于跨域问题，直接被灭
解决方法：通过服务器返回较实时的网站预览图的方式显示
