Most effective on-site-optimization

In showthread:
- h1 for Thread-Title
- h2 for Forum-Title

In forum:
--> here I need advice where to place it
(but it seems, that just h1 makes sense here)

This is my code:

PHP Code:

<if condition="$show['forumdesc']">
 <table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
 <tr>
  <td class="alt1" width="100%"><strong><h1 class="descr">$navbits[lastelement]</h1>
</strong> 
<h2 class="descr2">$foruminfo[title_clean]</h2>
<span class="smallfont">$foruminfo[description]</span>
</td>
 </tr>
 </table>
 
</if> 


As I am not a Pro in HTML, can you tell me how I get those lines closer together?

And second:
Where do you place h1 in forumhome-code?

Thanks!

Thanks!

I believe, that h1/h2 in showthread did really help me, so I am very interested in the second part of it

Still looking for answers on the last 2 posts
Thanks a lot!
