WCAG 1.3.1
Info and Relationships Accessibility isn’t only about avoiding violations — it’s about ensuring your product can be used confidently by everyone. This guide explains the principle of this rule, shows what goes wrong in real-world code, and provides a verified fix that meets WCAG and the European Accessibility Act (EAA).
Why this matters and how to fix it
Why this matters
There must only be one <main> landmark per page so assistive tech can jump directly to the primary content.
How to fix this issue
Remove extra <main> elements or change their roles to <section> or <article> without role='main'.
Automated detection · Manual review recommended
Developer guidance
Verify with NVDA or VoiceOver: pressing 'D' (landmark) should only stop once at 'main'.
