Fixing widget area position just like the menu area

Hello,

I’m updating an site and i found a problem with some code.

The original site have a custom area with that code:

<div id=”loginhome”>
<?php if (!(current_user_can(‘level_0’))){ ?>
<form action=”http://www.rodosys.srv.br/login/valida_formulario_login.php&#8221; method=”post”>
<spam style=”font-size: 11px; color: #999;”>E-mail</spam> <input type=”text” name=”email_login” id=”email_login” value=”” size=”20″ />
<spam style=”font-size: 11px; color: #999;”>Senha</spam> <input type=”password” name=”password_login” id=”password_login” size=”20″ />
<input type=”submit” name=”submit” value=”Login” class=”button” />
</form>

<?php } else { ?>

<spam style=”font-size: 11px; color: #999; “>Olá <?php $user_info = get_userdata(1);
echo ‘ ‘ . $user_info->user_login . “\n”;

?>| Sair </spam>
<?php }?>

</div>

I add this code in the header.php but I’m using a floating menu. How can I fix that div with the menu area?
