Banner Landmark
A banner landmark identifies site-oriented content at the beginning of each page within a website. Site-oriented content typically includes things such as the logo or identity of the site sponsor, and site-specific search tool. A banner usually appears at the top of the page and typically spans the full width.
            
ARIA 1.2 Specification: banner landmark.
Design Patterns
- Each page may have one 
bannerlandmark. - The 
bannerlandmark should be a top-level landmark. - When a page contains nested 
documentand/orapplicationroles (e.g. typically through the use ofiframeandframeelements), eachdocumentorapplicationrole may have onebannerlandmark. - If a page includes more than one 
bannerlandmark, each should have a unique label. 
- The HTML 
headerelement defines abannerlandmark when its context is thebodyelement. - 
                      The HTML 
headerelement is not considered abannerlandmark when it is descendant of any of following elements:articleasidemainnavsection
