In Webkit, you can set HTML and BODY tags to transparent, but you still get white. Maybe it is some sort of security restriction, to prevent one page from appearing to be part of another that it is hovering over. WebKit allows a transparent background in certain situations (Dashcode widgets use this, for example). I think the initial viewport color should be up to the user agent. The recently-discussed view modes proposal has a mode, "floating", in which the background is transparent: <http://www.w3.org/TR/view-mode/#view-modes> Simon
