I have now moved the documentation for all my plugins to GitHub. While it's evolving, I'm making greater use of CSS. What I'm looking to do is to use one CSS file to support all my repositories. In fact, I'd like to be able to move several common elements to their own HTML files so that I only need to edit one file to make changes to common stuff. Apparently, this is easier said than done with GitHub. Has anyone figured out a way to share files across multiple repositories without getting into complicated stuff like submodules? Maybe it's just not possible. The closest thing I've been able to come up with is to put the CSS file in Dropbox, but that seems like bad form.
Much appreciated,
Dave
