This course will introduce you to jQuery, a framework for building interactive web pages with animations, visual effects, and advanced functionality. You will start with a brief introduction to the course and jQuery. 

Next, you will explore the core concepts in jQuery, such as event-handling, animations, and in-browser manipulation of the document object model. 

Finally, you will learn about the AJAX framework in jQuery for dynamic content loading in web pages. On top of that, you will be working on an interactive project throughout the course with quizzes and challenges at the end of each chapter.

The Complete Guide to jQuery

In this lesson, we will explore different methods in jQuery that allow the user to **traverse sideways** in the DOM tree. Given the initial selection, these methods allow the user to query for **sibling** elements.

We will work on the web page shown below throughout the lesson. The web page consists of a `div` element with five child elements. These five elements, `a`, `span`, `p`, `h3`, and `ul` are _siblings_ of each other. 

Explore different jQuery methods such as siblings(), next(), prev(), nextAll(), prevAll(), nextUntil(), and prevUntil() that traverse sideways in the DOM tree.
