There have been some questions regarding this topic before but I am a bit lost and I would appreciate someone to explain this to me in a different way.
Context: I am using twitter bootstrap in my rails app (without Less, not familiar with Less or what it is but that's a separate issue)
I have been teaching myself CSS and when looking at the application.html.erb file in my rails app it calls certain classes such as "nav-bar" and "container-fluid nav-collapse". I am trying to find the css file where these classes are defined (so that i can customize them) but I cannot find it. So far I have tried the bootstrap_and_overrides.css and application.css.scss files but couldnt find the navbar class. Also I have tried these links: Bootstrap CSS Editing Editing navbar text color in twitter bootstrap but I wasnt able to have any luck.
