Understanding heading level diffs in print/online

[mattf]

I just today realized that I don't know how it is that Flare gives the h1 of a topic a smaller-than-h1 font-size in print outputs when that topic is used as a subsection of another section. It makes sense that in the online help, each title appears as an h1 when you open that topic, but I don't know by what mechanism that same title is printed with a smaller font-size when I compile the PDF, where it becomes just a nested subsection. Years ago, I used to include two top-level headings in each topic, and they were different heading levels, and conditioned for online and print. It was clunky, and I'm not sure now that I had to do that, but I did it and it worked. I haven't done that in years, and it only occurred to me today to wonder how Flare is making all this work automatically. Is it looking at the TOC level the topic is being used for and then cascading a change in the font-sizes for every heading level in that topic to adjust down in size by one level?

Can anyone explain this to me? I'd like to fiddle with my print output heading sizes, but I'm not even sure what they are, given this puzzle.

Thanks,
-Matt

To answer the question at the end of your first para: Yes

There is a setting in PDF targets to "use the TOC depth for heading levels". This link should help:

Yes. Basically, top level "books" in your PDF output will have the settings for H1 applied. Next-level-down books/topics will have the settings for H2 applied. Next-level-down books/topics will have the settings for H3 applied, and so on.

So it's not just adjusting the font size. It's actually using your settings for H2, H3, H4, etc. to apply the styles, based on how far down in the tree the topic appears.
