Here's a simple linkbutton example. It is not specific to the SBSK, but easily modified.
<style type="text/css">
A.button
{
background-image: url('images/bbg.gif');
background-repeat: repeat-x; background-color: #3399ff;
border-color: #0f8bdc; border-style: solid; text-decoration: none;
border-width: 1px; color: white; cursor: hand; font-size: 11px; margin: 4px;
font-family: Verdana,Arial,Helvetica,sans-serif; padding: 3px 12px;
}
A.button:hover
{
background-image: url('images/bbgh.gif'); color: black;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div style="height: 50px" >
<asp:LinkButton ID="LinkButton1" runat="server"
CssClass="button">Roll Over Me Now</asp:LinkButton>
</div>
</form>
</body>
</html>
