Baseline 2023

Newly available

Since August 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The offset-distance CSS property specifies a position along an offset-path for an element to be placed.

Try it


/* Default value */
offset-distance: 0;

/* the middle of the offset-path */
offset-distance: 50%;

/* a fixed length positioned along the path */
offset-distance: 40px;

/* Global values */
offset-distance: inherit;
offset-distance: initial;
offset-distance: revert;
offset-distance: revert-layer;
offset-distance: unset;

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%.


<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%;
