pt is worse. IE can't resize it either, and it depends on both DPI and resolution, not just resolution, making its ultimate size even more difficult to predict. > Common accessibility and usability practice > is to allow visitors the freedom to adapt font sizing to their personal > preferences. I don't think common is the best choice of word for that sentence, unless you take the word common to mean something merely more than rare. It really isn't that common yet except among students of accessible design. Best or good would be better choices. > Pixels are not a relative unit; they're as absolute for screen rendering > as point sizes are for the printing press. IOW, the problem is that px is not relative to anything inside a browser viewport, the only place the term relative has relevant meaning in the world of CSS. Unfortuately, the CSS spec makes people think px is a relative unit :-( http://www.w3.org/TR/CSS21/syndata.html#value-def-length -- "Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof..."
