1.3.1 — Info and Relationships

Scenario

Setting

A photo-sharing app's upload screen

What’s wrong

PDF: untagged documents, wrongly tagged headings/tables/lists, reading structure absent.

Example

During an audit of a photo-sharing app's upload screen: PDF: untagged documents, wrongly tagged headings/tables/lists, reading structure absent.

Why it matters

Screen-reader, braille, and reading-tool users who depend on coded structure rather than visual layout. On a photo-sharing app's upload screen specifically, they can't tell how the page is organized.

How to test

Run the PDF through Adobe Acrobat's Accessibility Checker or the built-in Tags panel: untagged documents, or wrong heading/table/list tags, fail.

How to fix

Tag the PDF (headings, lists, tables, reading order) or re-export from an accessible source.

Outcome

Fixed, a visitor to a photo-sharing app's upload screen can move through the content with confidence.

Who is affected

Screen-reader, braille, and reading-tool users who depend on coded structure rather than visual layout.
