I'm currently working a masterpage layout for a PDF document in RH. Does anyone have any examples of attractive, easy-to-implement masterpages for PDFs? Or does Adobe have a database or examples built in the RH?
Master pages are more about creating headers and footers plus default text for new topics. Once linked to a topic, any changes to the header and footer will be picked up when you generate but changes to the default text would not apply. It is just that, the default text, and you would not want it to override what you have written.
What makes a topic look good is more down to the CSS applied. There is no database that I know of but the sample projects do have a CSS that you can use if you like them.
Please always mention your version of RoboHelp when posting. I know you have said 2019 but there are two versions of that, Classic and New UI. In this case it doesn't matter much but often it can make the difference between getting a quick answer or someone having to ask which.
