The rotate3d function for CSS specifies a 3D rotation by the angle specified in last parameter about the [x,y,z] direction vector described by the first three parameters.
A direction vector that cannot be normalized, such as [0,0,0], will cause the rotation to not be applied.
<rotate3d()> =
rotate3d(
<number> ,
<number> ,
<number> ,
[ <angle> | <zero> ]
) <number> An integer or zero or more decimal digits followed by a dot (.) followed by one or more decimal digits. The first character may be preceded by a sign (- or +). The last character may be succeeded by an exponent (e or E) and an integer.
<angle> A number with a unit: deg (360 degrees in a full circle), grad (400 gradians in a full circle), rad (2π radians in a full circle), or turn (1 turn in a full circle).
<zero> Represents a literal number with the value 0.
