Ho risolto, ora nel validate non ci sono più errori, ma ho un problema, vi scrivo il codice html, e quello css qua:
Codice PHP:
<?php include("functions/mobile.php"); ?>
<!DOCTYPE html>
<html>
<head>
<title>Moolsh</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="css/moolsh.css">
</head>
<body>
<div id="header" onclick="location.href='login.php'">[url="login.php"]Login[/url]</div>
<div id="logo">
[img]images/moolsh.png[/img]
</div>
<div id="home">
<form action="searchfilm.php" class="search" method="get">
<div>
<input type="text" class="search" name="q" placeholder="Cerca.." autofocus="autofocus" required="required" />
<input type="submit" class="go" value="">
</div>
</form>
</div>
</body>
</html>

La compatibiltà è stata estesa al massimo su tutti i browser, l'unico problema è in opera, che sul tasto della ricerca compare un bordo di 1px nero! In allegato anche l'immagine, il bordo compare solo quando sono con il cursore nell'imput per il testo! Sapete quale può essere il problema?? Grazie!
