Goal

• Facilitate the identification of content that has already been visited.
• Facilitate the identification of content that has yet to be explored.
• Encourage users to navigate to new pages.

Implementation

Apart from the navigation menus, do not apply the same default CSS styles for unvisited links (a or a:link selectors) and for visited links ( a: visited selector). To do this: either provide a specific rendering for the links visited, or do not indicate a rendering rule for them (the default browser style can then be applied without difficulty).

Control

In each page containing hyperlinks:

• Check that the : visited selector is in the CSS style sheets and used, and that the style used is different from that applied to a or a: link or else;
• Check that the : visited selector is not in the CSS stylesheets to let the default browser style apply
