I made a custom skin.  The skin has a Dark Blue background colour.  The ContentPane has a white background and needs to be 500-px wide.  I added a another Content Pane called FlashPane above the ContentPane that has a transparent background colour.  When I have no content in the ContentPane, there is still a 1-pixel high white line showing on my skin.  How do I make this white line go away?   It is a table layout.  You can see what I mean here:

Below is a HTML Snippet from the Skin:

<td class="right-content"><table width="100%" border="0" cellspacing="0" cellpadding="0">
 <tr valign="top">
  <td id="HeaderPane" runat="server"></td>
 </tr>
 <tr valign="top">
  <td class="menu-pane">[SOLPARTMENU]</td>
 </tr>
 <tr valign="top">
  <td class="flash-pane" id="FlashPane" runat="server"></td>
 </tr>  
 <tr valign="top">
  <td class="content-pane" id="ContentPane" runat="server"></td>
 </tr> 
 <tr valign="top">
  <td class="copy-pane">[COPYRIGHT]&nbsp;&nbsp;[TERMS]&nbsp;&nbsp;[PRIVACY]&nbsp;&nbsp;[USER]&nbsp;&nbsp;[LOGIN]</td>
 </tr> 
 </table>

 </td>

Sytle:

flash-pane {
background-color: transparent;
padding:0;
}
.content-pane {
 background-color: #ffffff;
 padding-left:20px;
 padding-right:10px;
 padding-top:5px;
 padding-bottom:5px;
 font-size: 12px;
 font-family: Verdana, Arial, Helvetica, sans-serif;
}

If you cange the code from:

<td class="content-pane" id="ContentPane" runat="server"></td>

to:

<td >
    <div class="content-pane" id="ContentPane" runat="server">
    </div>
</td>

and remove the padding from the CSS for the contentpane, then it renders okay.

Now you could add the padding to the container, since that's not rendered at all if you don't put anything in the contentpane

Thank you very much.  Implementation is so simple, why are ideas so hard to come by?
