For link colors, place the following code (assuming you like my
particular color choices) in Common.css:
/* link appearance - note: "underline" means underscore */
/* and "active" means selected (mouse down) */
/* unvisited and initial defaults */
a:link {color: blue !important }
a:link { text-decoration: underline !important }
a:link:hover { background-color: yellow !important }
/* active links */
a:link:active { color: red !important }
/* visited links */
a:visited { text-decoration: underline !important }
a:visited { color: red !important }
a:visited:hover { background-color: yellow !important }
