I'm trying to host an already build jekyll website on github-pages.
The reason for this is that I want to combine it with another statically generated website (doxygen html).

When I let github use jekyll to generate the website, it works great. But If I generate it myself locally and push it to a branch with a .nojekyll file, the results seems to be missing css or a theme (not a web dev here, so dont know much about it).

Any idea how to make this work ?

Already generated jekyll can be seen here: https://f3d-app.github.io/f3d-doxygen-site/

Website is supposed to look like that: https://f3d.app
