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 offset-path you can define a specific path of any shape you want. You then animate it along that path by animating offset-distance, and can choose to rotate it at any point using offset-rotate.

Basic example

html
<div id="motion-demo"></div>
css
#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%;
  }
}
