Hello!



I see a web page as consisting of two structures: the navigation and the
content structures. The user alternates between them, not thinking much of
which is the higher or lower, but aware of that one is the navigation, the
other the content. In this respect there can be one h1 for the navigation
and one h1 for the content. But for other reasons, such as search engines
and screen readers , the h1 should appear only in the content structure. The
dilemma can be solved by other mark upp than h1 in the navigation part, such
as style and logo for the site title. And than sparcely use of h2, if a
complex navigation structure.



Best regards

Bo Nilsson
