I am working on this website. There are some strange things going on though. I have a absolute positioned div (top: 0, right: 0) called panel which is showing in Chrome but not in FF and IE. Then furthermore are there on a few pages (the Artist, Events) a gallery which are working fine in FF and Chrome but in IE I get a very strange stair effect. Does anyone see in my CSS what I am doing wrong?

Thank you in advance
