The HTML in the project is brittle, problematic for consumers and parsers, confusing to developers and designers, and future-unfriendly. I encourage you to spend some time researching the reasoning behind HTML and markup in general, including why it's important to use id and class names that describe the content (rather than the presentation) and HTML elements other than div. They exist for a reason.

Think about this: I can see from the linked page that you understand how adding type="password" to an input makes some consumers, like various web browsers, treat that field differently. There's a lot of stuff like that in HTML.

If you want a short intro that also explains some of the "why" behind various aspects of HTML5, read this: http://www.abookapart.com/products/html5-for-web-designers

The HTML5 spec also has a lot of info ( http://www.w3.org/TR/html5/grouping-content.html#the-div-ele... ). For example:

> Authors are strongly encouraged to view the div element as an element of last resort, for when no other element is suitable. Use of more appropriate elements instead of the div element leads to better accessibility for readers and easier maintainability for authors.
