Master pages can be nested, with one master page referencing another as its master. Nested master pages allow you to create componentized master pages. A site might contain an overall (Root) master page that defines the look of the site. One or more child master page can be inherited from this root master page. This child master page can be used as the master page for different content pages.

Child master page has the file name extension .master, as with any master page. A content page contains content controls that are mapped to content placeholders on the child master page. The child master page contains content controls that are mapped to content placeholders on the Root master page.
