Emil Bjoerklund is the Technical Director at digital design consultancy inUse, where he's usually busy building websites-or helping clients and co-workers better their craft. Emil created his first HTML page on Geocities in 1997, but got confused by the mess of table tags. Coming back to the web in 2001, he found this magical thing called CSS and has been fascinated by it ever since. For the last decade, Emil has been building websites professionally, hacking on anything from client-side JavaScript to server-side Python, but always with a special place in his heart for good old HTML and CSS. Emil's writing and advice on CSS has been published in Net Magazine and on CSS Tricks. He also writes about (mostly) web-related stuff on his blog at thatemil. Show Less
