Modern technology often makes subpixels available. It is unclear how they should relate to the pixel concept of CSS, which is rather vague - it's not simply a screen pixel (and don't ask me what it really is by CSS specs). But in addition to this, there is no logical necessity for turning font-size values to an integral multiple of a pixel even if we assume that everything on screen consists of atomic pixels. The font-size value does not specify any dimension of any character. Instead, it is a conceptual reference value, the height of the font. Thus, you could well have a e.g. font size of 11.0px as different from 11.4px in the sense that the actual character sizes vary at least for some characters. > Note that the rounding-point for em/% to screen-pixels is not the same > across browser-land, so calculate in +-1px variation. There is indeed a lot of variation, and it also depends on the units used. What's puzzling is that IE seems to _truncate_ e.g. 11.9px to 11px instead of rounding it to 12px. -- Yucca, http://www.cs.tut.fi/~jkorpela/ ______________________________________________________________________ css-discuss [EMAIL PROTECTED] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
