I have a help system in RH 2017, where I am using Responsive HTML5 format/output. I have done some customizations, changes to the CSS, master page, header logo, added dynamic filters, and so on so forth. This however is a PoC.
I want to roll it out/apply it to an actual production help, which is currently in a web help format.
Is there anyway to make a template from the PoC and then apply/import the template on to an existing web help? Or does it need to be redone?
HTML5 layouts are created in an entirely different way so no you cannot export a web skin and import it. You have to start with a supplied HTML5 layout and customise that. It is theoeretically possible to create your own but it takes seriously advanced skills.
Also be aware the calls to the help have to change as well.
