Well, it might be an option to use these <div>s but, on the other
hand, they do help to keep a structure. And once you have already
used them the question is whether they all should look the same...
Luigi, the point is using an element for its purpose. If you have no
purpose for using a div, or any other element, why use it? If you want to
mark up a division in a document, say an area that is for a menu, header,
or footer, then, by all means, use a div. But just to use a div because
it's a div is like using blockquote just because some user agents indent
the content, but it has no semantic meaning.
