I had made a post about 7 months ago, on an exact same problem. I have gone over that thread and can not seem to replicate the solution.

Here is the old thread:

If you go to www.defstatic.com , and scroll to the bottom, you will see my issue. The page nav buttons do not at all work right. Besides the fact that I screwed up the border, the active buttons have the default site a:link and a:hover settings.

Here is my code, I will try to spare anything unnecessary.

Code:
.back_button {
	float: left;
  text-align: center;
  font-size: 11px;
  font-weight: bold;
  color: #000;
  border: 3px double #80C9FF;
  width: auto;
  background: url(../images/button_bg.png) repeat-x;
  padding: 0px 10px;
  line-height: 20px;
  margin: 1px;
}

.back_button a:link, .back_button a:visited {
color: #000;
text-decoration: none;
}

.back_button a:hover {
color: #000;
text-decoration: underline;
}


.pagenav {
  text-align: center;
  font-size: 11px;
  font-weight: bold;
  color: #000;
  border: 3px double #80C9FF;
  width: auto;
  background: url(../images/button_bg.png) repeat-x;
  padding: 0px 10px;
  line-height: 20px;
  margin: 1px;
}

.pagenav a, .pagenav a:link {
color: #000;
text-decoration: none;
}

.pagenav a:hover {
color: #000;
text-decoration: underline;
}

.pagenavbar {
	margin-right: 10px;
	float: right;
}

#footer {
	text-align: center;
	padding: 3px;
}

ul
{
margin: 0;
padding: 0;
list-style: none;
}

li
{
line-height: 15px;
padding-left: 15px;
padding-top: 0px;
background-image: url(../images/arrow.png);
background-repeat: no-repeat;
background-position: 0px 2px;
}


td {
	text-align: left;
	font-size: 11px;
}



body {
	margin: 15px;
	height: 100%;
	padding: 0px;
	font-family: Arial, Helvetica, Sans Serif;
	line-height: 120%;
	font-size: 11px;
	color: #fff;
	background: #0066b3;
}

/* Joomla core stuff */
a:link, a:visited {
	color: #BFE4FF; text-decoration: none;
	font-weight: bold;
}

a:hover {
	color: #80C9FF;	text-decoration: underline;
	font-weight: bold;
}
i thought this would show up correctly, but nothing changes.
