CSS not working in IE

cssfirefoxinternet-explorersafari

Been working on this site for some time now, works perfectly on Mac and PC Firefox, as well as Safari. However, IE is making the site almost blank – any ideas on what is going on? Any workarounds?

Thank you in advance for your help!

Your html is invalid in many ways. Please fix that first.
