I feel like I'm missing something...browser incompatibility

You probably haven't heard people talking about this on on the Ruby on Rails mailing list because these are not Ruby on Rails-specific issues. It sounds like you should take some time to study up on these areas. Though they're getting a bit old, I recommend Jeffrey Zeldman's "Designing with Web Standards" and Eric Meyer's "Eric Meyer on CSS".

Online references include A List Apart[1] and the css-discuss mailing list and wiki[2]. There are plenty of other resources online as well.

Actually I have found IE7 to be my worst problem. Most CSS hacks have
been well explored on IE6 and IE5, but
IE7 includes a whole lot more incompatibilities. I have spent more
time on futzing with CSS to get it to work on IE7, than it took me to
write the rails app in the first place!

I even started using tables for layout again (I know gasp!!), because
IE7 broke all my nice CSS formatting.

The biggest problem which I never solved was a nice thumbnail layout
using CSS which worked on everything but IE7, on IE7 the thumbnails
were no longer clickable. That was the last straw that took me back to
using a table.

This is the gallery CSS as you can see works great except on IE7 you
can't click the thumbails!

Just one example of the pain I have been through! Why can't everyone
use Firefox :wink:

be sure you aren't allowing IE to operate in quirks mode (see
http://www.quirksmode.org/css/quirksmode.html for a discussion)
