    jQuery Wookmark

    The first thing that hits you when you visit Pinterest is "Whoa, the columns are the same width and the photos are cut to fit just the way they should."  Basic web users probably think nothing of it but as a developer, I can appreciate the...

    Create a Brilliant Sprited, CSS-Powered Firefox Animation

    Mozilla recently formally announced Firefox OS and its partners at Mobile World Congress and I couldn't be more excited.  Firefox OS is going to change the lives of people in developing countries, hopefully making a name for itself in the US as well.  The...

    I've covered the ins and outs of event delegation within JavaScript a few weeks ago but most developers utilize JavaScript frameworks so I thought I'd take a few moments to show you how to implement this wonderful event strategy with the MooTools, Dojo, and jQuery...
