Help colouring an echo output

[Jamier101]

I'm trying to echo back a result in white although I seem to have something wrong, can someone please help?

<div id="user_box">
 <?php 
//if($id!=""){ 
//echo 'Logged in as: '. $rowAccount['username'];
//echo '<input type="button" name="Button" value="Logout" onclick="document.location.href=\'logout.php\'"/>'; 
//}
if(isset($_SESSION['id']) && !empty($_SESSION['id'])){
echo "<font color='white'> . 'Logged in as '.$rowAccount['username'] . </font>";
echo '<input type="button" name="logout" value="Logout" onclick="document.location.href=\'logout.php\'"/>'; 
}
//else{
//}

?>
 </div>

No sooner had I posted than I realised my mistakes:

<div id="user_box">
 <?php 
//if($id!=""){ 
//echo 'Logged in as: '. $rowAccount['username'];
//echo '<input type="button" name="Button" value="Logout" onclick="document.location.href=\'logout.php\'"/>'; 
//}
if(isset($_SESSION['id']) && !empty($_SESSION['id'])){
echo "<font color='white'>" . 'Logged in as '.$rowAccount['username'] . "</font>";
echo '<input type="button" name="logout" value="Logout" onclick="document.location.href=\'logout.php\'"/>'; 
}
//else{
//}
?>
 </div>
