Alex Libby has plenty of experience in IT support, and 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 the open source movement, and in particular experimenting with CSS/CSS3 and HTML5. To date, Alex has written three books (one on HTML5 Video, one on SASS CSS, and another on JQuery Tools). LESS CSS Preprocessor How-to is his fourth book.
