Salve.
Guardate qui: http://neogpt.altervista.org/blog/
Sia con chrome, sia con mozilla, sia con explorer, il form di ricerca viene piu basso.
Questo è lo style.css:

codice:
body {
	font-size: 62.5%; /* Resets 1em to 10px */
	font-family: 'Lucida Grande', Verdana, Arial, Sans-Serif;
	background: #d5d6d7 url('images/kubrickbgcolor.jpg');
	color: #333;
	text-align: center;
	margin-top: 0px;
	}

#pagina {
	width: 900px;
        }
		
#header {
	background-image: url(images/header.gif);
	height: 100px;
	width: 900px;
}
		
#menu {
	background-image: url(images/menu.gif);
	background-repeat: no-repeat;
	height: 50px;
	text-align: left;
	font-size: 16px;
	color: #fff;
	
}
#menu-t {

Mentre questo è il pezzo in cui è contenuto l'header:
codice:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes(); ?>>

<head profile="http://gmpg.org/xfn/11">
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />

<title><?php wp_title('&laquo;', true, 'right'); ?> <?php bloginfo('name'); ?></title>

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" />
<link rel="alternate" type="application/rss+xml" title="<?php printf(__('%s RSS Feed', 'kubrick'), get_bloginfo('name')); ?>" href="<?php bloginfo('rss2_url'); ?>" />
<link rel="alternate" type="application/atom+xml" title="<?php printf(__('%s Atom Feed', 'kubrick'), get_bloginfo('name')); ?>" href="<?php bloginfo('atom_url'); ?>" /> 
<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />
</head>
<body>
<div style=" margin: 0 auto;" id="pagina">
<div style=" margin: 0 auto;" id="header">
</div> 
<div style=" margin: 0 auto;" id="menu">
<div id="menu-t">

<div id="cerca"><?php include (TEMPLATEPATH . '/searchform.php'); ?></div>
</div></div>

Vorrei che il modulo di ricerca sia allineato con le scritte del menu.
Cosa sbaglio?
Grazie.
