7 Principles of Accessibility, and How to Do It
Headings
Basic Principle
Headings are a quick way to ensure your content is arranged in a logical order. By properly formatting headings, people can use their screen reader to get an overall sense of the page content, and can skip to relevant passages as needed. Without headings, the only option is to read the page in a single block.
Questions to AskExamples
- Does my page have headings?
- Is there only one
h1per page? - Can I easily scan the text of my heading levels?
- Do the heading levels skip unexpectedly?
