Question

css3 animation最多能写几个动画属性

.fall1{

-moz-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
-ms-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
-webkit-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
}
这有三个动画，除了ie11，其它现代浏览器都能顺利执行以上三个动画，前缀都加了但到了ie11就不能执行第二个动画(即fall1，不是动画名和duration的原因) 是不是ie11有什么需要注意的地方？急！！

Answer 1

将animation的属性分开写，一起写的话IE11会不生效

Answer 2

把animation放在最上面
.fall1{
animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
-moz-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
-ms-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
-webkit-animation:fallDown .5s linear forwards,fall1 .5s .6s linear forwards,topAndDown linear 1s 1.1s infinite alternate;
