Although not programmers, every web designer needs to know at least a bit of JavaScript to do decently in one’s career. XHTML and CSS are great, but they can only do so much for a web page. Adding the interactivity and/or special effects that JavaScript can allow can not only enhance a design, but also lead to a more pleasant user experience.

In this post, we’ll cover some JavaScript features (and trends) that focus more on user experience and design elements themselves.
