Madelief,
Yeah look at the order bluranj has given. With the <style> </style> change it to link visited hover active...i created a CSS quickly...
<style type="text/css">
<!--
a:link { font-family: Verdana, Arial, sans-serif; font-size: 10pt; font-style: normal; line-height: normal; color: #CC0000; text-decoration: none}
a:visited { font-family: Verdana, Arial, sans-serif; font-size: 10pt; font-style: normal; line-height: normal; color: #666600; text-decoration: none}
a:hover { font-family: Verdana, Arial, sans-serif; font-size: 10pt; font-style: normal; line-height: normal; font-weight: normal; color: #3333FF; text-decoration: underline}
a:active { font-family: Verdana, Arial; font-size: 10pt; font-style: normal; line-height: normal; font-weight: normal; color: #66CCCC; text-decoration: none}
-->
</style>
