Breadcrumbs or breadcrumb trail is a navigation aid used in user interfaces. It allows users to keep track of their locations within programs or documents. The term comes from the trail of breadcrumbs left by Hansel and Gretel in the popular fairytale.

Websites

Breadcrumbs typically appear horizontally across the top of a web page, often 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. A greater-than sign (>) often serves as hierarchy separator, although designers may use other glyphs (such as » or ›), as well as various graphical treatments.

Typical breadcrumbs look like this:

Home page > Section page > Subsection page

or

Home page : Section page : Subsection page

or

home page : section page 1 : section page 2

Types of breadcrumbs

There are two types of web breadcrumbs:

• Location: location breadcrumbs are static and show where the page is located in the website hierarchy.
• Attribute: attribute breadcrumbs give information that categorizes the current page.

Usability

Location breadcrumbs are not necessarily appropriate for sites whose content is so rich that single categories do not fully describe a particular piece of content. For this reason, a tag may be more appropriate, though breadcrumbs can still be used to allow the user to retrace their steps and see how they arrived at the current page.

Cookie crumb

Some commentators and programmers alternatively use the term "cookie crumb" (or some variant) as a synonym to describe the previously mentioned navigation technique. Cookies are pieces of data stored in a web browser machine by the visiting websites in a HTTP cookie file. However, cookie crumb is rarely if ever referred to as this token of data. This is another technology used on the web that is different from the navigational method.

Operating systems

Current file managers like Windows Explorer (from Windows Vista onwards), Mac OS's Finder, Nautilus, Dolphin, Thunar and SnowBird allow breadcrumb navigation, often replacing or extending an address bar.
