It is definately not the same as the demo your website.
I cannot see what I’m doing wrong.
Even if I change line 60 to the line as you suggested above I get a very weard layout.
Edit: I had the compatability view on in IE10. Sorry. I’m going to test some more now.
Thank you for your response! I tried to do this and now I believe there are no html markup errors left. Still the site responds very weird in IE10. Where do you think this comes from?
