Trying to Change Link Colors in a Theme… (believe it's broken)

So I am trying to change the colors of links in my Blog (I am using a third party theme). However the normal code I am used to looks like this instead…

[please mark the code using the ‘code’ button or backticks]

.page-link {
	margin: 20px 0 22px 0;
	}

.page-link a:link, .page-link a:visited {
	background: #f1f1f1;
	color: #300;
	font-weight: normal;
	padding: 0.2em;
	text-decoration: none;

When I change the color in there is DOES NOTHING to the actual links appearance, ANY link for that matter.

Any thoughts?

Shouldn’t the code look more like:

a:link{
text-decoration: none;
color:#333;
}
a:hover{
text-decoration: underline;
color: #333;
}
a:visited{
text-decoration: none;
color:#333;}

?
