Back in 2009, the WebKit development team proposed a new extension to CSS that would allow Web page elements to be displayed and transformed on a three-dimensional plane.

Outside of WebKit, however, none of the other browser makers seemed to show much enthusiasm for it, so it’s remained a fairly niche and underused feature.
