I want to use this theme on github pages, but css won't render (and also links in the menu are not working) when I open link https://urbanzrim.github.io I've read that only few themes are supported by github pages. Is this true?
If not, can someone help me modify this theme to work? This is the repository of the theme: https://github.com/urbanzrim/airspace-jekyll. I know this was already a topic few times here, but I really don't understand what's going on.
