Rule n° 136 - The website applies a different style to visited and unvisited links.

By default, browser style sheets provide different colours for visited and non-visited links. It is quite legitimate to change this unseemly blue and purple, but why not keep this difference which is useful to the visitor?

  • 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.


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).

  • Check that the : visited selector is not in the CSS stylesheets to let the default browser style apply
