Alex Libby is from an IT support background. He has been involved in supporting end users for the last 18 years in a variety of different environments, and he currently works as a technical analyst, supporting a medium-sized SharePoint estate for an international parts distributor based in the UK. Although he 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 several books for Packt Publishing, including a video on HTML5 and books on jQuery UI. This is his seventh book with Packt Publishing.
