Master pages could help reduce the amount of work involved in creating numerous pages with the same basic layout.
Master Pages
Master pages are a part of ASP.NET 2.0 which allow you to define a common layout for the text and graphic content on a web page. For example, a master page could be used
to standardize the headers and footers across all of the web pages in a particular site. The layout for a master page is contained in a single file that can be inherited by
other Web pages. This feature allows the developer to create a consistent look and feel, as well as standard behavior for shared controls, across an entire application.
Sitefinity uses master pages to control the layout of pages within a site, but the user cannot edit the master page through Sitefinity. In order to edit the master page
for a site, open the site in Visual Studio.
