User interface libraries are better choices than collecting random JavaScript plugins from all around. Moreover, most JavaScript plugins do not integrate well with each other.
These libraries provide widgets that seamlessly integrate with each other, delivering a consistent, high quality look and feel. In addition, all widgets are guaranteed to work on multiple devices and browsers ensuring maximum compatibility.
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, jQuery UI is the perfect choice.
This book is ideal for developers who are well versed in CSS, JavaScript and HTML. Other than these, it does not require previous experience with the library itself nor jQuery.
The authors describe thoroughly uncommon topics such as the ThemeRoller and the CSS Framework that allow developers and designers to extend the UI library looks and adapt it to existing styles within an existing application.
Conclusion
jQuery UI 1.10: The User Interface Library for jQuery is a great cookbook for Web application developers who are looking a go-to reference of the jQuery UI library. It doesn't make assumptions, its thorough and current.
