<hn > ... </hn >
Specifies a heading that briefly describes the section it
introduces. There are six levels of headings, from
h1 (most important) to
h6 (least important). HTML syntax requires
that headings appear in order (for example, an
h2 should not precede an
h1) for proper document structure. Doing so
not only improves accessibility but aids in search engine optimization
(information in higher heading levels is given more weight).
