Blank Sidebox as Linked Graphic Only

[gjh42]

In your stylesheet, make a pair of rules for the particular link, like this:

#products a {
    display: block;
    height: 33px;
    width: 142px;
    background: url(../images/productbutton.gif);
    }

#products a:hover {
    background: url(../images/productbuttonhover.gif);
    }

Adjust to taste.
Replace the #products with whatever the identifying tag is.
