You use the piece you want then scale it. For distance, make it smaller, for viewing something that is on the side you shrink it in width while leaving the height alone, this gives the illusion that it is slanted.
It would not be possible to do true 3d with this because you would need to scale something into a trapezoid which HTML can not do.
