同样我想在 100％上动画旋转， code>和 0％与旋转如果可能。

  @keyframes bounceAndRotate { 
 0％{
 transform：rotate（0deg）; top：-20px;

 25％{
 transform：rotate（00deg）; top：-10px;

 50％{
 transform：rotate（0deg）; top：0px;

演示


I am trying to create animation with this arrow that will move up and down and also rotate or change its direction on 0% and 100%. But what I got so far is that arrow will rotate for sec on 100% and then return back to previous direction. So basically what I am trying to do is, arrow should point up on its way up and point down on return or on its way down. Can I do this with just CSS animations?

DEMO

On way up arrow should have this direction and on way down this oneAlso I want to animate that rotation on 100% and 0% with rotate if its possible.

解决方案

Just Change the animation with below code

@keyframes bounceAndRotate {
  0% {
    transform:rotate(0deg);top:-20px;
  }
  25% {
     transform:rotate(00deg);top:-10px;
  }
  50% {
     transform:rotate(0deg);top:0px;
  }
  75% {
     transform:rotate(180deg);top:10px;
  }
  100% {
    transform: rotate(180deg);top:20px;
  }
}
