Which practice supports navigation for learners who rely on screen readers?

• A. Clear headings and semantic markup
• B. Auto-playing video
• C. Small font
• D. Complex nested layouts

Answer: (A)

Structuring content with clear headings and semantic markup supports screen reader navigation. When a page uses proper headings (like H1, H2, H3) and semantic elements (header, nav, main, article, section, aside, footer), screen readers can build a navigable outline of the page. This lets learners who rely on these tools jump between sections, skip to the main content, and understand how information is organized without listening to every line. Good semantic markup also communicates the roles of elements to the screen reader, making navigation more predictable and efficient.

Auto-playing video disrupts this flow. It can start issuing audio or steal focus, which makes it harder for screen readers to read the page content and for the user to control what they hear or see.

Small font and complex nested layouts don’t specifically aid navigation for screen readers. Very small text affects visual readability more than navigation, and complex layouts can hinder navigation if they aren’t properly labeled and structured. Clear headings and semantic markup directly support how screen readers move through and interpret the page.
