I am perturbed by the fact that I have worked so long on this template, it’s looking so great in FireFox – but IE SUCKS!

Ugh. I am pretty new to this design thing and just thought that I would take a peek at how it looks in IE, since I just recently switched to Firefox this week.

How can it be that the same colour looks like two totally different shades in a different browser? I wish I knew what to do to fix it. Anyone?
