I am using 12px (pixel) and if you adjust the size in netscape 7, the size increases! I thought pixel was pretty absolute...is there a unit that will not change in size if the user changes the browser font size in netscape 7?
Funny, I always regarded IE's inability to resize text that has been specified in px as a bug in IE. After all, if people try to resize your page to read, it means they need to do so because the text is too small (eg, the people who are older or can't see so well). I'm sure they know that if they resize the page, everything becomes distorted.
But regarding your question: as far as I know, I don't think there's a way to do this with browsers like Netscape/Mozilla, Opera, etc. Of the graphical browsers, only IE disregards the user's wishes.
