<?php
if(isset($_POST['mehet'])) {
$message= '';
$the_name= mysql_real_escape_string(strip_tags($_POST['nev']));
$comment = mysql_real_escape_string(strip_tags($_POST['comment']));
$date = date('Y.m.d H:i:s');
if(!empty($comment) && !empty($the_name)) {
//mysql_query("INSERT INTO vendeg (name, comment, date) VALUES ('$the_name', $comment', '$date')") or die(mysql_error());

.guestbook_content {
width: 100%; <-- drop this rule
height: 100%;
padding: 5px;
}
#box {
width: 628px;
}
You gave child div width: 100% + padding 5px, which makes = 100% of parent div :628px + 5px left padding + 5px right padding so child div is 638px wide. Just drop 100% width on child. All you need is padding.
Here is jsfiddle with your situation: http://jsfiddle.net/crg2U/2/
And here is with droped 100% width on child : http://jsfiddle.net/crg2U/3/
