In web design the breadcrumb trail is a navigation aid used in user interfaces. It gives users a way to keep track of their location within programs or documents. Breadcrumbs typically appear horizontally across the top of a web page, usually below title bars or headers. They provide links back to each previous page the user navigated through to get to the current page or—in hierarchical site structures—the parent pages of the current one. Breadcrumbs provide a trail for the user to follow back to the starting or entry point. Here is an example of the Moodle Breadcrumb Trail.
