Where can I find site's CSS file?

[OriyanJ]

I'm working on a website, got my admin rights. I'm trying to change some classes in the site's CSS code but I cannot find it anywhere. Is there a folder which I can have a look at the CSS?

Excuse me if I sound too newbish, I'm kinda new to that.

Use Firefox Firebug to identify your css file

if you do need help finding it WITH firebug, download the extension in firefox, then click on the little bug icon in the top right. That should open a box at the bottom of your screen. Then click on the button that has a blue arrow pointing towards the middle of a blue box. That should allow you to analyze your elements on the page and it should tell you the location of their respective css class locations. If their locations are in bootstrap.css, you will have to make a new class in your template css folder to override this (@experts: if I'm wrong about this part, please correct me).
