I already have a username.github.io repository for my personal blog, and now my goal is to create another github-hosted jekyll page using a completely different theme I found. Here's the link to the theme I'm using: https://github.com/jeromelachaud/freelancer-theme
So I created a new repository on my machine and on github, connected the local repository to the remote github on, created an orphan gh-pages branch, and then forked the freelancer-theme and cloned it into the folder of the new repository I created while on the gh-pages branch. I used a command to move all the files (except the git init i think) into the parent folder of the new repository. I deleted the freelancer-theme fork folder and installed the most recent version of Jekyll with gem install jekyll. Then I ran jekyll serve and the site renders perfectly on my machine. Made some modifications, still renders fine with new modifications. After pushing those changes to the gh-pages branch of my repository on github, I now go to username.github.io/nameofmynewrepository and I get a site with all the components of the theme but the css doesn't seem to be working.
Has anyone worked with this theme and do they know the possible cause? It's very sparse on documentation.
Here is the url for my github page with the stylesheets not working: http://mpron.github.io/mybrotheriswrong/
And here is my new repo on the gh-pages branch: https://github.com/mpron/mybrotheriswrong/tree/gh-pages
