PJ: Kynn, good explanation, but do you have any information on which browsers support ems and exes? The resource I use at http://webreview.com/wr/pub/guides/style/mastergrid.html is somewhat detailed and lists Nav4 -partial, IE3- partial, IE4- yes, IE5- yes, Opr3- yes on the Windows platform, but is also confusing when listing exes as quirky on all browsers because exes are not technically one half of ems per the note? [See the last section on the page at 6.1 Length Units ] They also have a nice test suite at http://www.w3.org/Style/CSS/Test/current/sec61.htm Regards, Phill Jenkins IBM Accessibility Center - Special Needs Systems http://www.ibm.com/able
