Angle class abstract

The <angle> CSS data type represents an angle value expressed in degrees, gradians, radians, or turns. It is used by CSS functions like rotate() and in gradient angles.

Positive numbers represent clockwise angles; negative numbers represent counter-clockwise angles. Common units are deg, rad, and turn.

Examples (CSS): 90deg, 3.1416rad, 0.25turn.
