Property offset

Is a shorthand, and specifies how to animate an
element along a path

This property is a shorthand for the following CSS properties:

• offset-anchor
• offset-distance
• offset-path
• offset-position
• offset-rotate

Syntax

/* Offset position */
offset: auto;
offset: 10px 30px;
offset: none;

/* Offset path */
offset: ray(45deg closest-side);
offset: path("M 100 100 L 300 100 L 200 300 z");
offset: url("arc.svg");

/* Offset path with distance and/or rotation */
offset: url("circle.svg") 100px;
offset: url("circle.svg") 40%;
offset: url("circle.svg") 30deg;
offset: url("circle.svg") 50px 20deg;

/* Including offset anchor */
offset: ray(45deg closest-side) / 40px 20px;
offset: url("arc.svg") 2cm / 0.5cm 3cm;
offset: url("arc.svg") 30deg / 50px 100px;

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

Initial value as each of the properties of the shorthand:

• offset-position: normal
• offset-path: none
• offset-distance: 0
• offset-anchor: auto
• offset-rotate: auto

Inherited no

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

  to {
    offset-distance: 100%;
  }
}

  width: 50px;
  height: 50px;
  background-color: blue;
  offset: path("M 100 100 L 300 100 L 200 300 z") auto;
  animation: move 3s linear infinite;
}

img { // offset-path and offset-rotate
  offset: path('M 50 80 C 150 -20 250 180 350 80') 45deg;
}

img { // offset-path and offset-distance
  offset: path('M 50 80 C 150 -20 250 180 350 80') 150px;
}

img { // offset-path, offset-distance, offset-rotate and offset-anchor
  offset: path('M 50 80 C 150 -20 250 180 350 80') 150px -90deg / 0% 50%;
