Add underline to css style link?

[liunx]

How can I make this style underline when hovering and then be the color black after the surfer has clicked that link before?

Sorry, I'm slow.

<STYLE TYPE="text/css">
<!--
.navigation {cursorointer;cursor:hand;text-decoration: none;color:white;}</style>

Thanks,

JonI think this may be what you are asking for..

<style type="text/css"><!--
a.navigation:hover { text-decoration:none; border-bottom:1px solid #fff }
a.navigation:visited { text-decoration:none; border-bottom:1px solid #000 }
--></style>
