You'll need to post the offending code-- NOT the whole thing! Only enough to demonstrate the error. People need to see the html and css as they existed at time of posting, not as they will exist next week or at some future time.
fwiw, I fed the URL to the w3 validator and got 75 errors and 9 warnings. Some warnings can be ignored, but I think this batch are genuine typos.
By constrast, the CSS comes through as squeaky-clean CSS3 with not so much as a warning.
So start by hammering the html into shape.
