I am very new to inDesign and have been watching many tutorials. I have figured out on a basic level what master pages are. I set up a b-master for header/footers and a c-master for page numbering. I have different pages that I want different things on. When I go to apply one master, the other disappears and is not shown on my document. Is there a way to apply both the b and c master so that when I am working on my document I can see them both?
You need to create the master that will have items for every page on it first. The create a new master but when you do, choose to have it based on the first one.
Add the items you want to add on that page. On and on you go.
