URI

A uniform resource identifier (URI) is a standard way of referencing elements, objects, files, and so on.

The basic URI syntax is:

scheme://authority/path?query#fragment

URIs are either absolute or relative:

• An absolute URI contains a scheme and a colon separator.
• A relative URI is any URI that does not contain both a scheme and a colon separator. A relative URI can be a relative path, an absolute path, or just a fragment.

The fragment portion references an element that can be found within the same document as the URI. An example of this:

#redMaterial
