Calling it an “HTML5 website” is a bit of an overreaction IMHO. Other than the DOCTYPE, there’s not much “HTML5” to it. It’s just good old HTML, JavaScript and CSS, wrapped together in a document that happens to use the HTML5 DOCTYPE.
is actually how you declare an HTML5 doctype. They're also using the semantic HTML5 elements header and footer.Reference: http://dev.w3.org/html5/spec/syntax.html#the-doctype http://ejohn.org/blog/html5-doctype/
