WCAG 1.3.1 · Level A
Landmark One Main
- What is broken
- The page has no single main region, so there is nothing to jump to as "the content".
- Who it affects
- Screen reader users navigate by headings and landmarks; when the structure is wrong they lose the map of the page.
- How to fix it
- Wrap the primary content in exactly one <main> element.
