The general recommendation I've seen for fonts in stylesheets is to go with percentages rather than fixed point sizes.<br /><br />The reason being that the original idea behind stylesheets was that people would be able to have a local-side stylesheet which would define things like the standard size font they wanted to see on pages (e.g. for visually impaired users who would want extra large fonts). There is also the problem of point sizes displaying quite differently depending on the dots per inch of the monitor (e.g. this is why sites designed around Windows 96 dpi look terrible on a Macintosh or Linux which often assume a 72 dpi monitor).<br /><br />If you use a fixed point size for fonts in style sheets, then this overrides any settings of the local side stylesheet. But if you stay with percentages, then a font at "100%" will display in the size of the user's selected local stylesheet.<br /><br />Here's a good article on webreference about the problem and its recommendation to stick with just percentages.<br /><br /><A HREF="http://www.webreference.com/html/tutorial22/" target="_new">http://www.webreference.com/html/tutorial22/</A><br /><br />
