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)
.
Syntax
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.
rotateY(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.
