注销时，“我的页面包装器”是非常浅灰色的背景，它会扩展页面的100%，但一旦登录，它就会变小，并调整到成员栏的宽度

要测试以下用户帐户：

我怀疑您是否需要PHP，但这里是用于注销的

<? ob_start();session_start();include_once"config.php";
if(isset($_SESSION['username']) || isset($_SESSION['password'])){
    header("Location: http://creatorsparadise.herobo.com/index_logged.php");
}else{
if(isset($_POST['login'])){
$username= trim($_POST['username']);
$password = trim($_POST['password']);
if($username == NULL OR $password == NULL){
$final_report.="<a class='yep'>Please fill out all fields or&nbsp;&nbsp;&nbsp; </a><a href='www.http://creatorsparadise.herobo.com/index_logged.php'>Register Here</a>";
}else{
$check_user_data = mysql_query("SELECT * FROM `members` WHERE `username` = '$username'") or die(mysql_error());
if(mysql_num_rows($check_user_data) == 0){
$final_report.="<a class='yep'>This username does not exist.&nbsp;&nbsp;&nbsp; </a><a href='http://creatorsparadise.herobo.com/index_logged.php'>Register Here</a>";
}else{
$get_user_data = mysql_fetch_array($check_user_data);
if($get_user_data['password'] != $password){
$final_report.="<a class='yep'>Your password is incorrect. &nbsp;&nbsp;&nbsp;</a><a href='http://creatorsparadise.herobo.com/index_logged.php'>Register Here</a>";
}else{
$start_idsess = $_SESSION['username'] = "".$get_user_data['username']."";
$start_passsess = $_SESSION['password'] = "".$get_user_data['password']."";
$final_report.="<a class='yep'>Wait one moment...</a> <meta http-equiv='Refresh' content='2; URL=http://creatorsparadise.herobo.com/index_logged.php'/>";
}}}}}
?>

问题是您没有关闭
#header
，因此
#wrapper
将成为其子级而不是同级


然后，在
之前添加
以关闭
，如Oriol所述，您需要为#标题插入一个结束DIV

您需要在此处关闭#标题：
