I was wondering if anyone could help me..

I am making a site and I want the font size to be exactly 10pt, and to not be effected by what setting the user chose in their browser (largest to smallest). I know when I do size="2" that is effected by the users choice, but I thouhgt if I used css it would not be? Only links appear to be staying at the size I chose.

Thanks a lot anyone.
