This weekend, I finished reading jQuery UI 1.7 [The User Interface Library For jQuery] by Dan Wellman (released by PACKT Publishing). It's a follow-up to his jQuery UI 1.6 book, which I reviewed in early 2009. With a technology that is evolving as fast as jQuery, it's important that the documentation keep up such that we may know how to best leverage the tools that we have available; Dan's latest book, jQuery UI 1.7, does just that - bringing us completely up-to-speed with all aspects of the jQuery UI library. One thing that I was thrilled to see when reading this book was that after a brief introduction to jQuery and jQuery UI, Dan dives directly into the jQuery UI CSS framework. With the 1.7 release of jQuery UI, the library has become completely standardized in the way that the markup and CSS classes are applied to the library widgets. Not only does this make it easy to uniformly skin the widgets (via tools like ThemeRoller), it provides a good structure for anyone hoping to create their own custom user interface widgets.
