The Owen Hack hides CSS from Opera 5 and 6, but not Opera 7 (released today). However, my newly invented *7 hack hides CSS from Opera 5, 6, and 7 on Windows, and Opera 6 on OS X.

Note that I have nothing against Opera 7; it seems quite nice, and most of the bugs from the public beta seem to have been shaken out. I have no idea if there are any major CSS rendering bugs which would even require a hiding hack. It seems to handle all of the advanced demos in css/edge, which is impressive (and probably intentional).

One CSS bug which afflicted previous versions of Opera was the lack of simultaneous vertical and horizontal centering of background images (using background-position: center center). This is now fixed in Opera 7, which means that Oliver is now centered properly.
