Rotating in the Y direction css

asked Jan 31, 2022 in Technique[技术] by 深蓝 (71.8m points)

Trying to make a logo rotate in the Y direction as so :

@keyframes rotateLogo {
  0% {
    transform: rotateY(0deg)
  }
  // 50% {
  //   transform: rotateY(180deg)
  // }
  100% {
    transform: rotateY(360deg)
  }
}

.splashAnimation{
  animation-name: rotateLogo;
  animation-duration: 3s;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
}

However it ends up looking like this:

Thanks for reading, will post a jsbin but i imagine this is a known issue.

EDIT: This seems to happen as described because of an optical illusion. Is there any way to provide perspective in the rotation so as to provide some cues to the brain to perceive the rotation as unidirectional?

You need to add perspective to your logo's parent element in order to get the '3d' feel to it, like so:

body {
  perspective: 800px;
  background-color: #eee;
}

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

.splashAnimation{
  animation-name: rotateLogo;
  animation-duration: 3s;

  animation-iteration-count: infinite;
  /* animation-timing-function: linear; */
}

<body>
  
  <div class="splashAnimation" style="height:100%;display:flex;align-items:center;justify-content:center">
    <img style="width:100px;height:100px" src="http://brandmark.io/logo-rank/random/beats.png">
  </div>
  

</body>
</html>
