Hi,

any idea how i can express the following in CSS? Any help appreciated.

Code:
<html>

   <title>background</title>
 </head>
 <body topmargin="0" leftmargin="0">
  <table border="0" cellpadding="0" cellspacing="0">
    <td bgcolor="#66CC99" width="150" height="28"></td>
    <td bgcolor="#66CC99" width="15"></td>
    <td bgcolor="#66CC99" width="840"></td>
   <tr>
    <td bgcolor="#66CC99" width="150" height="15"></td>
    <td bgcolor="#6699CC" width="15"></td>
    <td bgcolor="#6699CC" width="840"></td>
   <tr>
    <td bgcolor="#66CC99" width="150" height="800"></td>
    <td bgcolor="#6699CC" width="15"></td>
    <td bgcolor="#ffffff" width="840">
    </td>
  </table>
 </body>
</html>
