The book takes you step by step into implementing jQuery user interface layouts. What I like most about the book is how the author explained a complex topic into a simple one. The book is complete and covers every aspect of user interface elements, from tabs, accordions, dialog boxes, slider, date picker, auto-complete, drag and drop, resizing, selections, sorting and other interface effects. I also like the part where the author would present a basic interface concept and discuss it and then have tutorials right after to help you fully understand the idea. I also found the use of screenshots very helpful.
Overall this book is excellent for beginners and contains useful examples along with some good in-depth explanations. My only concern is I can see some of the content in this book being outdated fairly quickly. If you use jQuery and want to start implementing user interfaces quickly and efficiently, you should consider picking up this book for sure.
