"I’ve been really getting into this jQuery phenomenon lately. jQuery is tightly tied to CSS, so if you are already comfortable with CSS and are looking for ways to expand your possibilities, jQuery is the place to be.

In the past few weeks, I’ve come across some great tutorials and roundups that have been helping me learn, so I thought I’d share."
