I would like to customize the underlying HTML/CSS for the "templates" in RH2019 (not the skins). Where are these files stored? There are several things in these templates that I hate and would like to fix but it involves messing with the template itself. Editing the HTML on specific pages is not good enough. Why there isn't a simple "create template" option for advanced users I do not know...
Can you expound on exactly what you mean when you say "Template"?
Are you referring to Master Pages?
Well when adding a skin, it has you select from a template (Azure Blue, Indigo, etc). I want to edit those. Basically I want to access all the hidden HTML/CSS robohelp doesn't seem to have an interface for.
It's probably in a bunch of files in the installation directory under resources/data. The 'template' folder seems likely, but I haven't looked in to it at all.
If you're game, back up everything both before and after, and be aware it could (will) be overwritten by Adobe during product updates.
In 2019 the layout, which is what I think you are referring to as a template, is not accessible in the way it was in earlier Classic versions. My understanding of the problem with the earlier implementation was that when Adobe found it necessary to make changes for whatever reason, the only way they could be introduced was along with a revised skin. That then meant that any customisation that users had made was lost.
In 2019 the underpinning layout can be changed by Adobe to fix bugs or add functionality without the skin losing any customisation. That was done in response to demands from those users who had put a lot of work into customising a skin, either through the interface or directly in the underpinning files, as that then had to be repeated from scratch.
