offset-rotate

Baseline 2022

Newly available

Since September 2022, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The offset-rotate CSS property defines the orientation/direction of the element as it is positioned along the offset-path.

Try it

Note: Early versions of the spec called this property motion-rotation.

Syntax

/* Follow the path direction, with optional additional angle */
offset-rotate: auto;
offset-rotate: auto 45deg;

/* Follow the path direction but facing the opposite direction of `auto` */
offset-rotate: reverse;

/* Keep a constant rotation regardless the position on the path */
offset-rotate: 90deg;
offset-rotate: 0.5turn;

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

auto: The element is rotated by the angle of the direction of the offset-path, relative to the positive x-axis. This is the default value.
<angle>: The element has a constant clockwise rotation transformation applied to it by the specified rotation angle.
auto <angle>: If auto is followed by an <angle>, the computed value of the angle is added to the computed value of auto.
reverse: The element is rotated similar to auto, except it faces the opposite direction. It is the same as specifying a value of auto 180deg.
