The value of the REL and REV attributes is a space-separated list of link types.

<a href-58<a href-16<a href-55

The REL and REV attributes define relationships between an anchor and the linked resource.REL defines a link relationship from the current document to the linked document while REV defines a relationship in the opposite direction.For example, indicates that the current document is a subsection of A percentage radius value for circular regions is calculated relative to the smaller of the object's width and height.If two or more regions overlap, the earliest specified region takes precedence.An A element cannot contain another A element, so one must be careful that named anchors do not contain link anchors.

Authors can use both the NAME and HREF attributes in a single A element to avoid this problem.

Examples of character encodings include ISO-8859-1, Shift_JIS, and UTF-8.

The ACCESSKEY attribute specifies a single Unicode character as a shortcut key for following the link.

In other words, a user should be able to pull all A elements from a document and still have an idea what lies behind each link.

Link text that contains The TARGET attribute is used with frames to specify the frame in which the link should be rendered.

The optional TITLE attribute can be used to briefly describe the contents of the link and is rendered as a "tooltip" by some browsers.
