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

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

句法

/* 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>

若 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 .
