Example

<h1>The Main Heading</h1> <!-- stuff --> <section> <h2>A Subheading</h2> <!-- sub-stuff --> </section> <section> <h2>Another Subheading</h2> <!-- sub-stuff --> <h3>A Subheading of a Subheading</h3> <!-- sub-sub stuff --> </section>

Headings do not have to appear in section elements, as shown in this example. If they do, however, because these section elements are semantically regarded as sub-sections of their parent, their content could begin with h1 elements and these headings would be regarded as sub-headings. It is quite valid to use h2 elements as show above, though. This maintains good semantics and has an added benefit of being backwards-compatible (with browsers that don’t recognise section elements). This is an approach employed by many sites, including this one.
