Alex Libby is from an IT support background. He has been involved in supporting end users for the last 15 years in a variety of different environments, and currently works as a Technical Analyst, supporting a medium-sized SharePoint estate for an international parts distributor, based in the UK. Although Alex gets to play with different technologies in his day job, his first true love has always been with the Open Source movement, and in particular experimenting with CSS/CSS3 and HTML5. To date, Alex has written five books based on jQuery, HTML5 Video, and CSS for Packt Publishing, and has reviewed several more (including one on Learning jQuery). jQuery UI 1.10: The User Interface Library for jQuery is Alex's sixth book with Packt Publishing.
