According to the Website, "jQuery is a fast, small, and feature-rich JavaScript library. It 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. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript."

Since jQuery is a JavaScript library, by simply including a link to the jQuery.js file in our HTML document, we can use all the features of jQuery to build a Website with neat animations and other features we see in modern Websites today.

Although Ch 10: jQuery is not covered in our textbook, there are lots of links in this chapter that I would encourage you to take a look at. You don't have to fully master jQuery - just learn what it is, and how it can help you to create effects seen on Websites today.

Additionally, you will want to check out jQueryUI. According to the Website, "jQuery UI is a curated set of user interface interactions, effects, widgets, and themes built on top of the jQuery JavaScript Library. Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice."
