Page should not have more than one banner landmark

landmarks/no-duplicate-banner · Best practice

Page should not have more than one banner landmark.

The banner landmark (typically <header>) identifies site-oriented content like logos and search. Only one top-level banner is allowed per page. If you need multiple headers, nest them inside sectioning elements (article, section, aside) where they become scoped headers rather than page-level banners.
