rotateX()
The rotateX()
CSS function defines a transformation that rotates an element around the
abscissa (horizontal axis) without deforming it. Its result is a <transform-function>
data type.
Try it
The axis of rotation passes through an origin, defined by the transform-origin
CSS property.
Note: rotateX(a)
is equivalent to
rotate3d(1, 0, 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.
Syntax
The amount of rotation created by rotateX()
is specified by an <angle>
. If
positive, the movement will be clockwise; if negative, it will be counter-clockwise.
css
rotateX(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.
