2. Most likely you nested the <body> in a wrong place.
3. You can't use a "#" as a link. <a href=#>Read More</a> It will only validate if you enter an URL or something after the #. So basically you gotta put the actual link here to get rid of this error.
4. Is same as #3
5. You missed a </div>
EDIT: now that i looked at it, i coudln't even find the <body> tag. First of all combine all of those <style> tags into one big one. Second of all the <body> tag goes below the </head> tag. according to error#2 your body tag is on line 182.
Thank you both of you, once you've pointed out one or two of the problems I had found them my self. I don't know how to code for the site to be compatiable with firefox and opera so it'd be best to view the page in IE. My page now has Validate HTML and CSS =))
