When (on my laptop) I make code, how do I do the CSS apart?

Question

Like a when I code with e.g. Bluefish, I want to have the CSS apart in a new window because I normally have a lot of CSS. Is it possible that when I have my CSS in one window and my HTML in another window that when I save both my webpage still works?
