句法

/* Default value */
offset-distance: 0;
/* the middle of the offset-path */
offset-distance: 50%;
/* a fixed length positioned along the path */
offset-distance: 40px;
					

<length-percentage>

A length that specifies how far the element is along the path (defined with offset-path ).

100% represents the total length of the path (when the offset-path is defined as a basic shape or path() ).

Using offset-distance in an animation

The motion aspect in CSS Motion Path typically comes from animating the offset-distance property. If you want to animate an element along its full path, you would define its offset-path and then set up an animation that takes the offset-distance from 0% to 100% .

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%;
  }
}
