Chapter 6. Interacting with the User
jQuery UI is a set of standard jQuery plugins that help you add interactive behavior to your Web site. This chapter starts with the jQuery plugins that can be used on almost any HTML element to drag, drop, resize, select, or sort the elements. These plugins add behavior without drastically changing the HTML.
Downloading and Installing jQuery UI
To begin using jQuery UI components, you need to include a separate library. jQuery UI is set up in modules. Modules are programmed in the same way as are third-party plugins.
