For the purpose of accessibility/scalability, I usually use ems to size my fonts, but I have a client who insists she does not want users to resize text on her website. So instead of ems I'm now using pixels, and I've added the "! important" flag in an attempt to lock it down within all browsers. Firefox still seems to allow you to adjust font size, though. Is there any way around this?
I have an idea. Make each page on the site one big image, or do it all in Flash. If your client refuses to allow people with accessibility issues to modify the font size, why not just go ahead and make the whole site inaccessible?
Ha, ironic -- I WAS already asked to render certain blocks of text as images as to retain consistent heights for wrapper divs. The accessibility arguement doesn't make a dent sometimes :P
