CSS is simply a list of rules for formatting things. As such, RoboHelp should allow you to simply import it and use it.
Have you actually tried it? Or is your question more rhetorical?
If you have tried it, did it fail in some way? If so, how?
Thanks for the quick reply. I haven't tried it yet but I plan on it. I agree that it sounds like it should work - just curious if anyone had tried and verified that it's do-able.
Bootstrap is a template language that relies on JS, itsn’t it? If so, you can use it, but the RH interface won’t support it. Also, you will need to make the JS file available for all topics as well.
One possible issue you may encounter: If RH doesn’t understand the CSS you provide, it may rewrite portions of the CSS to make it understandable for RoboHelp. So you may need to replace the CSS after generation with the correct CSS.
