Make My CSS Browser Compatible

This is a very easy and fast little project for someone that knows css. I designed a website with about 5 pages. My CSS works great with Internet Explorer. But it doesn't display well at all with firefox and other browsers. I need someone to make a couple of css compatiblity tweaks for me to make all pages display the same way across browsers. • Explorer 7.0 • Explorer 6.0 • Firefox 2.0 • Firefox 3.0 • Safari 3.1 • Explorer 8.0 Beta 2 • Google Chrome 0.2 Make sure it tests fine in all browsers.
