<style type="text/css">
a.weiss:link { font-weight:bold; color:black; text-decoration:none; }
a.weiss:visited { font-weight:bold; color:black; text-decoration:none; }
a.weiss:focus { font-weight:bold; color:white; text-decoration:underline; }
a.weiss:hover { font-weight:bold; color:red; text-decoration:underline; }
a.weiss:active { font-weight:bold; color:white; text-decoration:underline; }
a.schwarz:link { font-weight:bold; color:red; text-decoration:none; }
a.schwarz:visited { font-weight:bold; color:white; text-decoration:none; }
a.schwarz:focus { font-weight:bold; color:white; text-decoration:underline; }
a.schwarz:hover { font-weight:bold; color:black; text-decoration:underline; }
a.schwarz:active { font-weight:bold; color:white; text-decoration:underline; }
</style>
