Hi. I creating game on the base of css 3d transforms and some js as a proof of concept. This is game field: https://dl.dropboxusercontent.com/u/20810772/model/field.html In the -webkit- everything fine. But in the -moz- (Firefox 19) z-index have priority to 3d-transforms. So last element in the DOM always will overlap first element no matter what 3d positions they have. Is there any way to fix it? Set z-index for every element and recalculate them for any rotation is my worst nightmare. You may rotate scene with keyboard arrows. With all best regards.
