2.7 Use header elements to convey structure
WAI checkpoint 3.5
Full WAI text: "Use header elements to convey document structure and use them according to specification."
Headers are things like titles, section headings and row and column headings in tables, which are used to communicate the structure of the information on a web page. Headers should only be used to convey information structure, in accordance with the rules for use set out in the definition of the mark-up language. They should not be used to create presentation effects such as different sized text.
Many people navigate or skim through documents by reading the headings to get a feel for the structure and an overview of the content and scope of a document.
HTML allows you to specify a hierarchy of heading levels by using different header tags - H1, H2, H3, etc. The tag not only defines the hierarchical order of a heading, it also affects visual presentation, so that an H1 heading looks bigger and bolder than an H2 heading. Using the header tags to make non-heading text bigger and bolder can confuse users by making content which is not a header look like one. This makes it very difficult to gain an understanding of the structure of a document or page. Also, some screen readers will read content assigned as a header in a different tone of voice to other content on the page, providing users with important clues about document structure. Misusing heading attributes will therefore misinform and confuse screen reader users.
