Single-source layouts let you override the master page or the CSS when you generate output. For different output results, apply different master pages or a different CSS.
Each single-source layout except the Printed Documentation layout provides an option to apply master pages or CSS. You can choose to apply a master page or a CSS across all the topics in a project.note: For the Printed Documentation layout, you can apply only a different CSS.
•If you do not select the Apply To All Topics option, the master pages associated with individual topics take effect. If no master pages are associated with individual topics, RoboHelp applies no master pages when it generates output.
•If you choose to apply a master page, master pages associated with individual topics are overridden. The CSS associated with the master page becomes effective and overrides the CSS associated with all other individual topics.
•If you choose to apply a CSS, master pages associated with individual topics take effect. The selected CSS is applied to all the topics whether any master page is associated with them or not.
