First, put an ID on your div, it will make accessing it easier. Then just google for jquery add class and jquery remove class.

In addition to Solution 2:

Class is just a part of DOM, which can be fully controlled by JavaScript. One simple way of doing such things is using jQuery. Please see:
http://api.jquery.com/addClass/[^],
http://api.jquery.com/removeClass/[^],
http://api.jquery.com/toggleClass/[^],
http://api.jquery.com/category/css[^].

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery[^],
http://jquery.com[^],
http://learn.jquery.com[^],
http://learn.jquery.com/using-jquery-core[^],
http://learn.jquery.com/about-jquery/how-jquery-works[^] (start from here).
