offset-rotate - CSS: Cascading Style Sheets 编辑

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

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: .5turn;

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.
