I am still just beginning to wrap my mind around Cascading Style Sheets: the idea that a separate file should be created and edited in order to govern how some - or all - of the pages in a specific web site should appear to users. That all those web pages have to refer back to that file - a style sheet - to that end goal.

Learning how to design such a style sheet is one of my ongoing projects, both for my own web site's sake and for the sake of any graphic design jobs I hope to pursue.
