Usage notes

  • Heading information may be used by user agents, for example, to construct a table of contents for a document automatically.
  • 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.
  • You should consider avoiding using <h1> more than once on a page. See Defining sections in Using HTML sections and outlines for more information.
