People who use assistive technologies such as screen readers are able to browse through the "sections" of a website only through the use of headings and sub-headings (h1-h6) that give an invisible structure to the page. Without headings, web resources appear as one long paragraph to screen reader users. Consequently, locating and understanding information is difficult.
How should I use headers?
- When you structure the page with headers, start with having the same content for the page title and the H1.
- For each of the main sections of the page, label them as H2's and subsections as H3's and each subsection under that H4 and lower as needed.
