Applying new master page to all

[Tara5E92]

Hi - I am fairly new to RoboHelp so bare with me. I inherited this project from someone else, and I created a new master page to make the pages look and feel different. How can I apply this master page to all of the pages in my project?

Should I have just made the changes to the master page that is already applied? Any help would be appreciated!!

You can do that, but all that'll change in your existing topics are the header and footer. The body of your existing topics that have the new master page applied will remain/look as they were.

If you edit/update the header or footer of a master page at any time, the changes trickle out/down to any topics to which it's assigned.
