控制图片换有两种方法，分别是键盘和鼠标。
倒影控制-webkit-box-reflect:below 10px -webkit-linear-gradient(rgba(0,0,0,0) 40%,rgba(0,0,0,0.4));其中图片倒影分上下左右，below是倒影在图片下方 10px是距离图片10成倒影
3d成立体图transform-style:preserve-3d;注意只能定在父级
图片初始向下transform:perspective(800px) rotateX(-10deg);
思路：定义多少的图片N,for循环定义图片背景，图片定义一段时间出来timeout设定运动，键盘keydown控制下定义转的角度y，循环定义分别运动距离和角度。
键盘控制图片环：
