jQuery UI 1.5 released with a new approach to UI. Using the “simple” approach, we were only able to serve simple interaction modules, but not full featured UI widgets. The second problem was that some plugins came from external sources making the UI suite seem disjointed and inconsistent. found an approach that kept the simplicity of jQuery while making it possible to add full featured widgets to UI. jQuery UI 1.5 is a generic API that allowed for maximum flexibility while being amazingly simple and it is simple to develop plugins for that API.

One of the first things that a user typically wants to do when using new UI controls is “skin” them to match their site’s color schemes. ThemeRoller offers a unique approach to theming UI components specifically built for jQuery UI. With ThemeRoller, you can create your very own theme for your project within minutes. It’s completely intuitive, comes wich rich controls to change the color and design of each state, and then previews your theme with the actual UI components as you work.

You now have literally millions of combinations to chose from. Any theme you create can be reached by copying the URL at any point in your progress; and after you’ve played with it enough, you can click the download button and a ZIP package is generated with the css file, the images and a demo page.
