Alex Libby has a background in IT support. He has been involved in supporting end users for the last 18 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 he gets to play with different technologies in his day job, his first true love has always been the open source movement, in particular, experimenting with CSS/CSS3 and HTML5. So far, he has written several books for Packt Publishing, including one on HTML5 video and another on the jQuery UI. This is his eighth book.
