I don’t know of a specific reason why we don’t use <position> on perspective-origin. It looks like Gecko parses it the same way as transform-origin but without the z coordinate. WebKit and Blink use a special function just for perspective-origin. Both can probably use <position>. Would implementations be willing to change? Greetings, Dirk > > ~TJ >
