Annoying Text Size problem
So I have this website that I built and I mainly checked to see it looked in FireFox, which looked fine. However, when I checked the site in IE and Chrome, the text size was too big. So I tried fixing it, but now the text is too small for FireFox. I was setting my font in pixels, then I tried 0.8em. Now I tried at 10pt, but still experiencing the same problem.
This is how it currently looks. The one on the left is FireFox, and then Internet Explorer on the right.
And here's my CSS
Any help is appreciated. Thanks a lot.
