The link class can properly establish relationships on its own with other classes in the system and can have any number of characteristics.

For each pair of related objects, a link class creates a single instance of the class. The link class can properly establish relationships on its own with other classes in the system and can have any number of characteristics.

The:link Unvisited elements are represented using CSS pseudo-classes. Every unvisited href-property-equipped a> or area> element is matched.

A link relationship is a type of association or communication path in the UML. A link is a relationship between objects or instances of the classifiers or nodes, as opposed to an association, which is a relationship between two classifiers. Another example of a communication path between two nodes is a link relationship.
