hyperlinks in comments section

Hi everyone!
I was wondering if you could help with some simple css. I’m trying to add in a code in my *comments* css section that will result in coloured hyperlinks.

This is what I current have:

/* comments */
.alt {
margin: 0;
padding: 0;
background: #f5f5f5;
border-bottom: 1px dotted #ccc;
}

.commentlist { padding: 0; }

.commentlist li {
margin: 15px 0 3px;
padding: 5px 10px 3px;
list-style: number;
}

.commentlist p {
margin: 10px 5px 10px 0;
}

#commentform p {
margin: 5px 0;
}

.nocomments {
text-align: center;
margin: 0;
padding: 0;
}

.commentmetadata {
margin: 0;
display: block;
text-transform: lowercase;
color: #3366ff;
}

If anyone can help me add in a code for hyperlinks that would be much appreciated!
