offset-rotate

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

css

/* 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.
