rotateY()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

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

Try it

transform: rotateY(0);

transform: rotateY(45deg);

transform: rotateY(-0.2turn);

transform: rotateY(3.142rad);

<section>  <img          src="/shared-assets/images/examples/firefox-logo.svg"    width="200" /></section>

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

Note:rotateY(a) is equivalent torotate3d(0, 1, 0, a).

Note:Unlike rotations in the 2D plane, the composition of 3D rotations is usuallynot commutative. In other words, the order in which the rotations are applied impacts the result.

Syntax

css

Values

This transformation applies to the 3D space and can't be represented on the plane.		$(\begin{matrix} cos (a) & 0 & sin (a) \\ 0 & 1 & 0 \\ - sin (a) & 0 & cos (a) \end{matrix}) \left( \begin{array}{ccc} \cos(a) & 0 & \sin(a) \\ 0 & 1 & 0 \\ -\sin(a) & 0 & \cos(a) \end{array} \right)$	$(\begin{matrix} cos (a) & 0 & sin (a) & 0 \\ 0 & 1 & 0 & 0 \\ - sin (a) & 0 & cos (a) & 0 \\ 0 & 0 & 0 & 1 \end{matrix}) \left( \begin{array}{cccc} \cos(a) & 0 & \sin(a) & 0 \\ 0 & 1 & 0 & 0 \\ -\sin(a) & 0 & \cos(a) & 0 \\ 0 & 0 & 0 & 1 \end{array} \right)$

<rotateY()> =
