I have a repository already created on github where I publish a project by gh-pages. Doing tests in resolutions I need to make adjustments in the css but when entering the branch and pushes the changes, they are not saved !? ... what ... would it be happening?

I work with git, and I use gitlab the github commands are the same, so try commit, pull and push, believe me follow these steps solve that type of problems, from terminal you can commit like this:
commit -m "el comentario de tus cambios."
