To use Link-Rollover Effect, simply change around colors, fonts, and effects.  The more recognizable fonts are Verdana, Arial, and Helivectica.  With effects the five main ones are boldface, underline, overline, strikethrough, and typewriter.  Typewriter looks ugly, so does boldface.

The following is the script you add in between the head tags:

<style>
body {font-size: 10pt; font-family: Verdana}
a:link {text-decoration: underline; color: black} 
a:visited {text-decoration: underline; color: black} 
a:active {text-decoration: underline; color: black} 
a:hover {text-decoration: boldface, strikethrough, typewriter, overline underline; background-color: red; color: silver}
