Css glitch, help please

I have setup a Wordpress Blog with P2 prologue Theme ( http://wordpress.org/extend/themes/p2 ) on my blog at http://rebtweeter.com but there is 2 css glitchs for the Rebtweeter part:

1°) Fonts are too big for the form
2°) In Recent updates section, when you click on Reply, there is an alignement glitch.

So I need some css help as I'm not guru with that kind of stuff.

I just included a simple custom form inside post-form.php under <div class="sleeve_main"> this snippet

  <div id="postbox">

  <div id="main">
  <h2>Rebtweet (no registration needed)</h2>    

  <ul id="postlist">
  <li class="no-posts">    
  <!--
      <div class="avatar"><?php echo prologue_get_avatar( $user->ID, $user->user_email, 48 ); ?></div>    
  -->    

  <?php
   require_once $_SERVER['DOCUMENT_ROOT'] . '/form_include.html';
  ?>
  </li>
  </ul>
  </div>

  </div>

  <div id="postbox">

PHP:

 

Open up your style.css and find #postbox label:

#postbox label {
	color: #444;
	display: block;
	font-weight: normal;
	font-size: 1.6em;  // Make this number smaller.  Example: .6em
	margin-bottom: 6px;
}

// The following is new code for you to paste in to adjust the Reply labels...

#commentform label {
	font-size: 1.6em;  // Make this number smaller.  Example: .6em
}

Code (markup):

 

Hi thanks for help but it seems it wasn't enough to do the job

Finally as I was fed up I get rid off P2 form and keep just mine !

Still I don't understand why the font is bigger in the command field.

 

Oh well, you can't win 'em all.

 

Will have to dive into CSS learning deeply in coming weeks
