When I take a look at your site, it looks the exact same in every browser. Here is what I see – http://i.imgur.com/APBYtSe.jpg
I checked in Firefox, Chrome, Safari, and Opera and they are all showing up consistently. Did you already get this fixed, or are you seeing something different than what I am?
Your site is looking pretty good by the way. I like it! If you’re interested, make sure and add your site to the showcase when you’re done – http://appfinite.com/showcase-your-site/
