for the mac ... some of the really basic fonts that correspond to windows font software are:
mac ----- pc
helvetica --- arial
courier --- courier new
times -- times new roman
in the crazy world of design, i usually end up writing pages for "serif" or "non-serif" fonts. So i would code:
<font face="Times New Roman,Georgia,Times,Palatino,serif">
this way, if people have the specific fonts on their computers they'll see 'em, if not, it will go to the standard sarif or non-sarif font selected in their browser.
there are other generic font choices such as, "cursive", "fantasy" or "monospace". a bit of info on this is at: http://www.webfonts.com/tag/1998/08_07_98.shtml
if you want to check out some offerings from microsoft for both mac and windows you can check out:
don't forget these are in addition to the regular, included ol' system fonts. so people would have to download them to their computer to see the same results.
.... ah, just the tip of the iceberg ... hope this helps,
