All of the transform functions we have looked at so far are two-dimensional, operating on just the x and y axes. Transforms that operate in three dimensions, along the x, y, and z axes have also been proposed.
3D equivalents of all of the transform functions exist and usually just take an extra parameter, which corresponds to the vector of each dimension, and the angle. For example, a 3D rotation could be added using this code:
transform: rotate3d(0, 1, 0, 30deg);
As with 2D transforms, there is an all-encompassing matrix function that allows us to implement any of the other transforms and allows us to combine some of them together on a single element.
If, like me, you thought the 2D transform matrix, with its six parameters, was complex and perhaps a little hard to understand, wait till you start using the 3D matrix, which has 16 parameters in total!
At present, 3D transforms are supported in WebKit-based browsers and Firefox (with partial support for IE10), so we won't be...
