CSS motion path

The CSS motion path module allows authors to animate any graphical object along a custom path.

The idea is that when you want to animate an element moving along a path, you previously only had animating translation, position, etc. at your disposal, which wasn't ideal and only allowed for simple movements. With {{cssxref("offset-path")}} you can define a specific path of any shape you want. You then animate it along that path by animating {{cssxref("offset-distance")}}, and can choose to rotate it at any point using {{cssxref("offset-rotate")}}.

Basic example​

<div id="motion-demo"></div>
#motion-demo {
  offset-path: path("M20,20 C20,100 200,0 200,100");
  animation: move 3000ms infinite alternate ease-in-out;
  width: 40px;
  height: 40px;
  background: cyan;
}

@keyframes move {
  0% {
    offset-distance: 0%;
  }
  100% {
    offset-distance: 100%;
  }
}

{{EmbedLiveSample('Basic_example', '100%', 150)}}
