Master Web page or template created with ASP.NET; used for building multiple pages with the same layout; typically includes defined header, navigation, and footer sections as well as editable areas; constructed using HTML, just like a typical Web page.
When editing a Web page based a master page, the non-editable areas are shaded gray while alterable items are clearly shown. Editable areas can be defined by editing the master page directly.
