Reason for edit: codebox = holly

Okay, here's what the person did. She named those links individual names "add, block, etc", and then created normal link CSS according to that, like this for the add link:

CODE

.add a:link, .add a:visited, .add a:active {
    width: 70px;
    height: 35px;
    background-image: url("http://i174.photobucket.com/albums/w111/divoverlaycom/DIV/butyou/add1.gif");
    display: block;
    z-index:5;}
.add a:hover {
    width: 70px;
    height: 35px;
    z-index:5;
    background-image: url("http://i174.photobucket.com/albums/w111/divoverlaycom/DIV/butyou/add2.gif");
    display: block;}

She put height and width attributes accordingly to the images that she used to link. Also, she made the original link a picture [add] (first gif reference) and then made the hover picture [add with the strikeout] (second gif reference).
