Curved/rounded table headers

[j1mmy]

Right, I've identified the template as forumbit_level1_nopost:

<tbody>
	<tr>
		<td colspan="<if condition="$vboptions[showmoderatorcolumn]">4<else />3</if>"> 
                <!-- forcing space -->
                <img src="$vboptions[cleargifurl]" width="1" height="5" />
                </td>
        </tr>
</tbody>
<tbody>
	<tr>
		<td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">4<else />3</if>">
			<if condition="$childforumbits">
			<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
			</if>
			<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
			<if condition="$show['forumdescription']"><span class="smallfont" style="font-weight:normal;">- $forum[description]</span></if>
			<if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
		</td>
	</tr>
</tbody>
<tbody>
	<tr align="center">
	  <td class="thead" >&nbsp;</td>
	  <td class="thead" width="100%" align="$stylevar[left]">$vbphrase[forum]</td>
	  <td class="thead" width="175">$vbphrase[last_post]</td>
	  <if condition="$vboptions['showmoderatorcolumn']">
	  <td class="thead">$vbphrase[moderator]</td>
	  </if>
	</tr>
</tbody>
<if condition="$childforumbits">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
$childforumbits
</tbody>
</if>

Now, just to be on the sale side, is this the code I need to edit?

<div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div>

Or is it this one:

<tbody>
	<tr align="center">
	  <td class="thead" >&nbsp;</td>
	  <td class="thead" width="100%" align="$stylevar[left]">$vbphrase[forum]</td>
	  <td class="thead" width="175">$vbphrase[last_post]</td>
	  <if condition="$vboptions['showmoderatorcolumn']">
	  <td class="thead">$vbphrase[moderator]</td>
	  </if>
	</tr>
</tbody>

Also, where would I enter the custom CSS? Would I need to put anything in the actual table header field

Everytime I try it, this happens
