如何将此PHP打印的HTML表单设置为保留在

标记内？

So I'm building a fairly simple login page for my website. Only the login form, an HTML form printed by PHP echo commands, doesn't want to stay in the HTML <p></p> tags. Here's the code:

<div ID="loginbox"><p> 
<?php
$db = mysqli_connect( $dbHost, $dbUser, $dbPass ) or die("Cannot connect to the server");?>

<?php      
if($_SESSION['authenticated']) { //// See if the user's logged in 
echo "You are logged in as $name "; //// If they are show message  
} else { //// if not logged show login form 
echo '<form action="login.php" method="post"><input type="hidden" name="ac" value="log"> '; 
echo 'Username: <input type="text" name="name" />';
echo '<br /> Password: <input type="password" name="password" />';
echo '<br /> <input type="submit" value="Login" />'; 
echo '</form><br />';
echo '<a href="registeruser.php">Don&#146;t have a login? click here to register</a>'; 
}
?>                
</p>
</div>

And here's the relevant CSS:

#loginbox {
border-radius: 15px;
color: black;
position:inherit;
width: 250px;
height: 100px;
margin-left: auto;
margin-right: auto;
margin-top: 55px;
}
#loginbox  > p {
border-radius: 15px;
background-color:white;
box-shadow:0 0 20px rgba(0, 0, 0, 0.4);
height:387px;
Width:500px;
top:60px;
left:50px;
font-family: palatino;
padding:50px 50px 37.5px 37.5px;}

#loginbox > form {    position: inherit;
z-index: 3;
top: 150px;
padding-left: 36px;
margin: 0 auto;}


#loginbox a:visited
{color:#010101;}

#loginbox a:hover
{color:#010101;}

#loginbox a:active
{color:#000000;}
