When I build HTML output using sphinx, it is possible to display h1 and h2 on separate pages, however, h3 is always displayed on the same page as h2. Does anyone know how to mak
So, we were able to make it work by adjusting the HTML template and the globaltoc setting.
Unfortunately, based on this note from the readthedocs.org irc channel one of the main devs said no, that's not possible.

If you want this support the only thing I can suggest is checking out MkDocs at http://mkdocs.org, however, you lose PDF building capability and some other LaTex support that's included in Sphinx.
Good luck!
