What is jQuery?
jQuery is “write less, do more” open source Javascript library.
Specialized for changing web page documents on the fly.
jQuery makes it easy to add action and interactivity to any web page.
jQuery makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.
jQuery is the core library. jQueryUI is built on top of it. If you use jQueryUI, you must also include jQuery.
