Using CSS you can change the way the anchor of the link looks.
Four states of the anchor text can be styled.
link: Affects unvisited links
visited: Affects links that your browser knows that you've visited.
hover: affects the link that your mouse is hovering over
active: the active link that has been selected by tabbing over.
Code:
<style>
a:link {color: #FF0000; font-weight: bold;} /* unvisited link */
a:visited {color: #00FF00} /* visited link */
a:hover {color: #FF00FF} /* mouse over link */
a:active {color: #0000FF} /* selected link */
</style> The above example makes the unvisited links bold.
