Breadcrumb navigation is a way to show you where you are in a website. It's like following breadcrumbs that someone left behind. Each breadcrumb is like a clue. They tell you which page you're on and the pages you've visited before. Think of it like a trail of breadcrumbs that leads you back to where you started. Breadcrumb navigation helps you easily find your way around a website and get back to where you were.
