Heading elements implement six levels of document headings, <h1> is the most important and <h6> is the least. A heading element briefly describes the topic of the section it introduces. Heading information may be used by user agents, for example, to construct a table of contents for a document automatically.

Usage note:

  • Do not use lower levels to decrease heading font size: use the CSS font-size property instead.
  • Avoid skipping heading levels: always start from <h1>, next use <h2> and so on. Also try to have only one first level heading on a page.
Content categories Flow content, heading content, palpable content.
Permitted content Phrasing content.

Permitted parent elements Any element that accepts flow content; don't use as a child of <hgroup> element, it is now deprecated

These elements include the global attributes.

The align attribute is obsolete, do not use it anymore.
