Throughout the first four chapters of this book, we have been using the .addClass() and .removeClass() methods to demonstrate how we can change the appearance of elements on a page. Although we discussed these methods informally in terms of manipulating the class attribute, jQuery actually modifies a DOM property called className. The .addClass() method creates or adds to the property, while .removeClass() deletes or shortens it.
