后记：

1.上下翻转是 X轴翻转(rotateX),左右翻转是Y轴翻转(rotateY);

2.backface-visibility: hidden;背面的隐藏;

3.圆点其实没有动是长方形的div rotate 做的;

4.重点：

　　如果想动态更改 animation-duration 的完成速度时间 有两个方法：

　　一、给旋转的对象换不同的class 更改 animation并且animation-name必须赋一个新的keyframes 否则不生效;

　　二、JS 修改 animation-duration、animation-name 两个值必须同时修改 并且 animation-name 必须赋一个新的keyframes否则不生效;;
