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 1.1 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:- article
- aside
- main
- nav
- section
