The rotateY() CSS function defines a transformation that rotates an element around the ordinate (vertical axis) without deforming it. Its result is a <transform-function> data type.

The axis of rotation passes through an origin, defined by the transform-origin CSS property.

Note: rotateY(a) is equivalent to rotate3d(0, 1, 0, a).

Note: Unlike rotations in the 2D plane, the composition of 3D rotations is usually not commutative. In other words, the order in which the rotations are applied impacts the result.


The amount of rotation created by rotateY() is specified by an <angle>. If positive, the movement will be clockwise; if negative, it will be counter-clockwise.



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