rotate()

The rotate() CSS function defines a transformation that moves the element around a fixed point (as specified by the transform-origin property) without deforming it. The amount of movement is defined by the specified angle; if positive, the movement will be clockwise, if negative, it will be counter-clockwise. A rotation by 180° is called point reflection.

Syntax

rotate(a)

Values

a
Is an <angle> representing the angle of the rotation. A positive angle denotes a clockwise rotation, a negative angle a counter-clockwise one.
