To maximize assistive technology compatibility, how should headings be structured?

• A. Each visual heading should be a properly marked programmatic heading level that matches the visual level.
• B. Headings can be any tag, with no relation to visual level.
• C. Headings should be avoided to simplify structure.
• D. Headings must all be H1 elements.

Answer: (A)

Using a semantic heading hierarchy where the programmatic heading level matches the visual presentation is essential for assistive technologies to accurately navigate and understand a page. Screen readers and other AT rely on the sequence and level of headings to construct an outline of the content, letting users jump between sections with confidence. When a heading looks like a subheading but is marked with a mismatched level or with a non-heading element, the AT outline becomes misleading, making navigation harder and content easier to skip or miss.

The best practice is to mark each visual heading with the appropriate heading element and ensure its level corresponds to how it appears on the page. This keeps the logical structure in sync with the user’s expectations, supports keyboard navigation, and provides a reliable map for AT and automated tools that summarize the page.

Using any tag without relation to visual level removes the semantic map AT uses to navigate; avoiding headings entirely eliminates the landmarks that help users orient themselves; forcing all headings to be the same level removes the necessary hierarchy that conveys the relative importance of sections.
