Make all of your changes to the respective style sheet and then run the following commands. If you add a framework or theme, those are usually placed in vendor/assets/stylesheets. I can replace the second command with git add vendor/assets.

1. Compile assets locally, run next command
    RAILS_ENV=production bundle exec rake assets:precompile
 
2. Commit and push the new changes
    git add public/assets
    git commit -m "vendor compiled assets"

3. Pull with rebase
    git pull --rebase heroku master

4. Push to heroku
    git push heroku master
