  100%{transform:rotateX(360deg);}
}

#rX:hover{
  animation-name:turnX;
  animation-duration:3s;
  animation-iteration-count:1;
}

@keyframes turnY{
  0%{transform:rotateY(0deg);}
  100%{transform:rotateY(360deg);}
}

#rY:hover{
  animation-name:turnY;

@keyframes turnZ{
  0%{transform:rotateZ(0deg);}
  100%{transform:rotateZ(360deg);}
}

#rZ:hover{
