A page banner is a quick way to add titles to your web pages. Page banners use the styles and graphics of a theme, if one is used on the current page; otherwise, the page banner just displays text, which you can format. Using a page banner inside a shared border is a way to quickly add titles to multiple pages in a web.
Before you can use page banners, you must set up your web's navigation structure in Navigation view. (A page banner will not be visible on a page unless the page is included in the navigation structure.) Page banners use the page titles from Navigation view; if you change this title for a page, its page banner label will also change.
After you add a page banner to a page, you can change the text that is displayed on it, and you can specify whether to display a graphic or just text. The page banner picture that will be displayed is the banner that is associated with the theme for that particular page.
