not really sure what you are looking for here......I looked at all of the url's you posted and i just can't seem to understand for sure what putting the page in the body means......sorry for my misunderstanding.
Are you wanting to ad a border around your page? if so, try this:
go to: Admin CP -> Styles & Templates -> Style Manager -> Common Templates (in the menu)
and in the header do this: <!-- border -->
<table border="2" align="center" cellpadding="0" cellspacing="0" bordercolor="#7B9AC6">
<tr>
<td>
<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>
<td align="$stylevar[left]"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
<td align="$stylevar[right]">
</td>
</tr>
</table>
<!-- /logo -->
<!-- content table -->
$spacer_open
$_phpinclude_output, Then go to your footer and do this <br />
<div class="smallfont" align="center">$vbphrase[all_times_are_gmt_x_time_now_is_y]</div>
<br />
$spacer_close
<!-- /content area table -->
<form action="$vboptions[forumhome].php" method="get">
