The word, in the fine tradition of late night technicians, was coffee. I was linking specifically to CB's second part of that column, the Don't Freeze Me Out. As for the discussion of when is a pixel a pixel, I don't know. These people are a hell of a lot smarter than me. CB is correct about the spec's definition of a pixel.

Only Opera can say if this is what they're doing with the mac version, or if it's a bug. An official statement would be helpful, but they're just one browser company, so that case is really just a detail that brings up something that may become a real issue. I do think the Opera font in mac is a bug. If they were using the relative pixel then all the rest of the px measurements would have been proportionally scaled, and they're not. If you declare a box 400px wide it comes out 400px, not downscaled like they did with the text.
