Use headings appropriately
Many people who use adaptive technology to access Web pages skim through documents by navigating headings. By using heading elements <H1> to <H6> to define the organizational structure of your page, you'll make the content more accessible to people with disabilities. Effective use of headings also promotes good indexing and searching with search engines.
- Use header elements for all headings. Don't use font size or bold type to indicate headings visually.
- Order header elements properly. For example, in HTML, <H2> elements should follow <H1> elements, <H3> elements should follow <H2> elements, etc.
- Do not "skip" levels (e.g., <H1> followed by <H3>).
- Use Cascading Style Sheets (CSS) instead of heading elements to change font sizes and/or styles.
