CSS refers to Cascading Style Sheets, which is really a fancy way to refer to the design elements of your site.
What CSS is, is simply a sheet that has all the design elements in one place, so that when the browser first loads it, that is it. It won’t need to keep on interpretating your design code instructions.
I was what you would call Old School, until learning CSS. This really is a much more effecient way to design a web site, to insure that you have more than just a simple style in place.
It takes your design elements to new levels. It also lessens the amount of code in your pages, which helps your SEO.
