Preparing DITA Source Documents : Assigning Custom Page Styles to Pages in DITA Source Documents : Understanding Page Styles
 
Understanding Page Styles
By default, each page generated by ePublisher is associated with the default page style defined in the stationery used by your ePublisher project. This means that typically you do not need to specify a page style for pages when you generate output.
For example, you may want to use one page style in your help system for all concept and procedure topic pages, and another page style for all context-sensitive window description topic pages in your help system. In this example, you can use the default page style for all of your concept and procedure topic pages, and then you can use a second custom page style defined in your stationery for all context-sensitive window description topic pages in your help system.
