The second to last link, when clicked, shows its default state which is to turn and remain a dark purple.
<div id="footer">
    <p><b>Logged in as:</b> <pre><?php echo showUser(); ?></pre></p>
    <p><b>Tracks rated so far:</b><pre><? echo showRatings(); ?></pre></p>
    <p><b>Withdraw from experiment:</b> <a href="kill_session.php">Click here</a>.</p>
    <p><b>Contact information:</b> <a href="mailto:#">d"""""""""".com</a>.</p>
</div>
My CSS is as follows:
#footer a {
    text-decoration: none;
}
#footer a:hover {
    color: red;
}
#footer a:active {
    position: relative;
    top: 2px;
    color: blue;
}
Its only basic, but improves it from the basic style. How can I make the visited link remain blue?
