Web Standard: On this Page/Table of Contents


"On this Page" is a table of contents, or a list of links, most often found at the top of the page, that links to information found further down the page.

Content Requirement

  • Use a table of contents on pages that contain more than one main section, and that are more than two screenfuls long.
    • As an introduction, before the contents list, write a short blurb for the page (one sentence may be sufficient) unless the information presented on the page is completely intuitive.
    • After the introduction, create a bulleted table of contents with links to each heading. If the page presents questions and answers, the links will be to the questions.
  • Capitalize only the first word of the anchored links.
  • If closely related information on this topic is available on other pages, a second “On Other Pages” bulleted table of contents may also be displayed (see Example 2 below).
  • A horizontal rule is added after the table of contents.
