Adding a link to a RSS feed

I added the piece of code to the bottom but nothing happened. See DBBL News under joomla.bc-marburg.de

/* joomla 3.0 */

.element-invisible {
display: none;
}

li.email-icon a {
display: inline-block;
width: 25px;
height: 25px;
text-indent: -9999px;
background-image: url(../images/emailButton.png);
background-repeat: no-repeat;
}

li.print-icon a {
display: inline-block;
width: 25px;
height: 25px;
text-indent: -9999px;
background-image: url(../images/printButton.png);
background-repeat: no-repeat;
}

small {
font-size: inherit;
}

.newsfeed-item {
margin-bottom:8px!important;
}

Maybe this will work:

Thx, that worked!
