How to rotate an icon at the end of animation?

Question

I found the following example https://codepen.io/lonekorean/pen/vYLNpoY to make the basic animation. But how can I rotate the icon used in the @keyframes duck animation at the end of @keyframes move animation.

.duck svg {
height: 100px;
}

.duck {
  animation: duck .2s linear infinite alternate;
}

.move {
    animation: move 10s linear infinite alternate;
}

@keyframes duck {
  from {
    transform: translateY(-7px);
  }
  to {
    transform: translateY(0px);    
    
  }
}
@keyframes move {
  from {
    transform: translateX(0) ;
  }

  to {    
    transform: translateX(400px) ;
  }
}

<div class="box move">

Maybe this is what you're looking for?

.duck {
  width: 100px;
  height: 100px;
  animation: duck .2s linear infinite alternate;
}

.duck svg {
  width: 100px;
  height: 100px;
}

.duck-rotation {
  width: 100px;
  height: 100px;
  animation: duck-rotation 20s linear infinite;
  transform-origin: center;
}

.move {
  width: 100px;
  height: 100px;
  animation: move 10s linear infinite alternate;
}

@keyframes duck {
  from {
    transform: translateY(-7px);
  }

  to {
    transform: translateY(0px);    
    
  }
}

@keyframes duck-rotation {

Answer 2

In general, you can combine multiple properties for transform: by simply adding them separated by a space, for example:

transform: translateX(400px) rotate(20deg);

But to be honest, I'm not sure what the result you want to achieve should look like.
