I think the point being made is not a site that has absolutely no HTML tags. Rather the distinction that the structure of the site is primarily css based rather than nested table based as is the case with a majority of the sites on the web now. You would still need HTML of course. But by using CSS you could make the code a lot less messy by removing the crazy nested tables that you have to use sometimes. Not only that, it'd probably increase the page load times by decreasing the page size. From what I've read however, there is limited support for this. CSS 2.0 is aiming towards making this a REALITY but most browsers apparently do not support 2.0 yet. We'll see what the future holds
