Fotomatic project

Hey! Im just starting the Fotomatic project and note there are two CSS files. I just wanted to double check that we should be linking both and if so, which should we use to edit the code?

I have read about linking multiple style sheets and understand that the sheet that is linked first will override the second one that is linked - could I just confirm that this is what is intended for this project please? Many thanks in advance! :grinning:
