The rotateY(angle) function is equivalent to rotate3d(0, 1, 0, angle).

Note the following:

  • The angle argument specifies the element's angle of rotation.
  • angle can be in degree, gradian, radian, or turn.
  • An angle argument consists of a number followed by the unit you wish to use—for instance, 45deg.
