The document provides an overview of learning how to use jQuery #3. It discusses using more events and combinations of events, CSS, effects, attributes and manipulations. It also covers samples and demos that combine these jQuery features, such as a "don't click twice" sample to disable a submit button, a tab sample to show and hide page content, and a "roll over" sample to change an image on hover. It concludes with a brief introduction to using Ajax with jQuery's load and get methods.
