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.
The rotateY()
CSS function defines a transformation that rotates an element around the
y-axis (vertical) without deforming it. Its result is a
data type.
Try it
transform: rotateY(0);
transform: rotateY(45deg);
transform: rotateY(-0.2turn);
transform: rotateY(3.142rad);
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.
