1、去掉div｛｝里面的 transform: rotate(0deg) ;
2、这一系列代码中只需要写一个过渡时间即可：
-webkit-transition:transform 4s ease-in-out 1s;
-moz-transition:transform 4s ease-in-out 1s;
-ms-transition:transform 4s ease-in-out 1s;
-o-transition:transform 4s ease-in-out 1s;
transition:transform 4s ease-in-out 1s;
正确示例：
-moz-transition: transform 0.8s ease-in-out;
-webkit-transition: transform 0.8s ease-in-out;
-o-transition: transform 0.8s ease-in-out;
-ms-transition: transform 0.8s ease-in-out;
transition: transform 0.8s ease-in-out;
3、旋转角度也要写出浏览器兼容样式：
正确示例：
-moz-transform: rotate(360deg);
-webkit-transform: rotate(360deg);
-o-transform: rotate(360deg);
-ms-transform: rotate(360deg);
transform: rotate(360deg);
