Document should not have more than one banner landmark
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
Multiple banners confuse screen reader users because they expect only one header landmark representing the site’s top-level identity.
How to fix this issue
Use one <header> element or one role='banner' per document. Remove or change extra banners to role='presentation' or a sectioning element.
Developer guidance
Global header belongs at the top of the DOM. Section-specific headers should not have role='banner'.
