Multiple Background CSS Animations
CSS background animation has been a hot topic for a long time, mostly because they look pretty sweet and don't require additional elements. I was recently asked if it was possible to have multiple background animations on a given element and the answer is yes...with...
![Referencing a Script’s Own Tag]()
Referencing a Script’s Own Tag
There are times when the contents of an external script may want to reference its own

![GitHub and Mozilla Work Process]()
GitHub and Mozilla Work Process
Nicholas Zakas sent out a call to Twitter asking developers who use GitHub as a primary CVS to share their working process. Mozilla uses GitHub for many (if not most, but I can't confirm that) mission critical web applications so I chimed in on...
