The following picture shows a family tree. With jQuery traversal, you can easily move up (ancestors), down (descendants), and horizontally (siblings) in the family tree, starting with the selected (current) element. This movement is called traversing the DOM.

Figure parsing:

An element is a parent and a child of an element

The element on the left is the parent, the child, and the descendant at the same time.
