[Plugin: upPrev: NYTimes Style "Next Post" Animated Button] upPrev not recognizing categor

Ok, I actually found a way to customize it. Made a few changes to the upprev_layout.css file. This is what the code looks like now.

#upprev_box {
    position:fixed;
    z-index:1000;
    bottom:0px;
    right:-400px;
    width: 360px;
    padding: 10px 20px 10px 10px;
    border-top: 2px solid #000;
    border-left: 1px solid #f0f0f0;
    background-color: #fff;
    -moz-box-shadow: 0 4px 10px #666;
    -webkit-box-shadow: 0 4px 10px #666;
    box-shadow: 0 4px 10px #666;
    -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, direction=270, strength=7)";
    filter: progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, direction=270, strength=7);
    _position: absolute;
    _top: 0;
    color: #004276;
    font-size: 12px;
    font-weight: bold;
    font-family: "Helvetica Neue", "Lucida Grande",
    Verdana, Arial, sans-serif;
}
#upprev_box h6 {
    margin:0 0 5px 0;
    color: #004276;
    padding:0;
    text-transform: uppercase;
    font: bold 10px arial,helvetica,sans-serif;
}
#upprev_box .num {
    color:#888;
    font-weight:normal;
}
#upprev_box button {
    border: none;
    padding: 0;
    position: absolute;
    top: 5px;
    right: 5px;
    width: 13px;
    height: 13px;
    background: #fff url('close_window.gif') no-repeat 0 0;
    text-indent: -999em;
    overflow: hidden;
    cursor: pointer;
}

I don’t know much about CSS so obviously, the above code needs more, because the box is still not the way I’d like it to be. I mean the main link isn’t dark blue. Also, I wanna align the text towards the left of the box.
