HTML and XHTML Pocket Reference, 3rd Edition

Name

h1, h2, h3, h4, h5, h6 — <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).
