Uso de los encabezados para mejorar la accesibilidad

El artículo Heading Structure For Accessibility explica cómo el uso de los encabezados puede ayudar a mejorar la accesibilidad de una página web.

Los consejos que proporciona son:

• Provide only HTML headings.
• Provide logical heading structure. Eg: H2 should follow h1, H2 or H3 should follow H2, H3 or H4 should follow H3 and so on.
• Page should at least have one H1 and it should represent the title of the webpage.
• The H1 of the page should be at the beginning of the main content.
• Only one level one heading on a webpage is recommended and maximum two level one headings if the website name also needs to be marked in every page of the website.
• If another H1 is placed in the web page it should represent the title of the website.
• It is better to start the page with higher level of heading.
• Never skip any level of heading.
• The primary and secondary navigations also can have headings but should be below the level of main heading. Ideally they should be H2 considering level one for main heading.
• Never use HTML heading for visual appearance.
