Sphinx Book Theme 0.4: custom header is missing

[PhilipVinc]

I have a sphinx website that uses sphinx-book-theme 0.3.x to which I added an additional non sticky header written in bootstrap 4.
See the website.

The header is taken from an Hugo bootstrap website and slightly modified in order to give the illusion that our main website (https://www.netket.org) and the readthedocs website are the same.

To use this header, I simply added the file assets/templates/sections/header.html with the relevant HTML code.

However, upon updating to the pre-release of sphinx-book-theme 0.4 this does not work anymore and the extra header is not displayed.

Is there some guide that could help me in the transition?

I think that this will be fixed when the pydata sphinx theme makes their next release, but the short version is: double check that the header doesn't have display: none attached to it. For now, I think that rule is active and that might cause your problem.

This PR is doing the updates for the new pydata theme if you wanna iterate over there:
