page-break control using HTML classes

[dhimmel]

Works for both print output and wkhtmltopdf.

I'm going to merge cause I want to use this feature downstream immediately, but revisions welcome.

Nice feature. What elements are supported? Is it primarily to be used alongside markdown headers?

[dhimmel]

Haven't tested it out too extensively, but any HTML element where pandoc accepts the {.page_break_before} syntax for should work. I tried adding .page_break_inside_avoid to image attributes to force the caption to be on the same page as the image, but the class only ended up being applied to the image and not the image+caption element.

For the example manuscript, would it work to add {.page_break_after} to the abstract instead of {.page_break_before} to the equations? I expect that is one of the most common uses, and it will persist even if someone deletes 02.equations.md.

That doesn't appear to work, but the following does appear to work:

<div class="page_break_after"></div>

Thanks for testing. We can leave it as is in that case. I think that HTML in the markdown files should be avoided as much as possible.
