title: What's the difference between jquery.ui.theme.css and jquery-ui.css?
body: <p>In a project I'm working on we have a /themes/ directory with all the jQuery ui-themes in it. I get that they overwrite certain styles of the base class, but why are there two different css files (jquery.ui.theme.css and jquery-ui.css)? AND why are they seperate? Do I need to include both, or just one?</p>
