Master pages allow common elements like headers, footers and navigation to be defined once and shared across multiple pages, reducing duplication. Content pages attach to a master page and define the customizable content areas using content placeholders. At runtime, the master page and content are combined into a single page for the user.

 Master pages are an easy way to provide a template that can
be used by any number of ASP.NET pages in your
application.
 In working with master pages, you create a master file that is
the template referenced by a subpage or content page.
 Master pages use a .master file extension, whereas content
pages use the .aspx file extension you’re used to; but content
pages are declared as such within the file’s Page directive.
 You can place anything you want to be included as part of the
template in the .master file.
 This can include the header, navigation, and footer sections
used across the Web Application.
 The content page then contains all the page content except
for the master page’s elements. At runtime, the ASP.NET
engine combines these elements into a single page for the
end user.
