Hi!
Thanks for the suggestions. I have tried 'smoothdude11' method:
all you have to do is change the margin to zero in the general tab.
but all I got was the borders of every individual topic within zone, not the whole zone border.
So instead I modified 'RicardoCorai' method, and in effect I got the border of the zone. I have now:
<table border="0" cellspacing="5" cellpadding="0" width="633" height="207" style="border-collapse: separate">
<tbody> <tr><td colspan="2">{date_time}<br />{top}</td></tr>
<tr valign="top"><td width="48%">{leading}<br />{module_position2}<br /></td><td width="52%" align="left">{more news}<br />
<table border="1" cellspacing="10" cellpadding="10" style="border-collapse: collapse" bordercolor="#cccccc"><tbody>
<tr valign="top"><td> {most popular}<br /><br /> </td></tr></tbody></table> </td></tr>
<tr valign="top"> <td colspan="2">{module_position3} </td> </tr>
<tr><td colspan="2"> </td></tr>
<tr valign="top"> <td colspan="2">{featured categories}</td> </tr>
<tr><td colspan="2"> </td></tr></tbody></table>
Thanks!
