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.
