CSS is great! It makes for simplied editing of a lot of things. One spot to change all syles. Awesome!

My Opinion CSS make your site coding more organize and solid. CSS separate content from presentation as much as possible. Making it more easy to understand the content area and the templates areas, so you could make different templates without affecting the content. For some astonishing examples of how this works, visit the CSS Zen Garden and try clicking some of the designs listed in the sidebar. All of the designs have exactly the same content; the only thing that's different is the CSS.
