I once tried breaking my css into files according to function (typography.css, color.css, layout.css). It ended up being a royal pain because when I added a new HTML element and I went to style it, I ended up having to duplicate the css selector for that element in three files. I also was constantly switching among the three files to work with one element's styles. So whatever you do, don't organize by function. :)
