jQuery traversal methods allow you to navigate through the DOM tree to find and manipulate elements. These methods provide a powerful way to access and manipulate elements based on their relationships to other elements. This tutorial covers the most commonly used jQuery traversal methods with detailed examples, explanations, and useful tips.
