包含html页面中的PHP echo或print语句的样式

Question

Part of my validation script spits error codes depending on the error. It includes displaying an html error page. The statements that print or echo out on the error page always push the page down and also seem to affect some odd things like font size etc. It by default always displays the echo statements at the top of the page in the center. Is there a way I can style this? I would like the error message to display at a certain areas within the html?

if((!$first_name) || (!$last_name) || (!$email_address) || (!$username)){
echo 'You did not submit the following required information! <br />';
if(!$first_name){
    echo "First Name is a required field. Please enter it below.<br />";
}
if(!$last_name){
    echo "Last Name is a required field. Please enter it below.<br />";
}
if(!$email_address){
    echo "Email Address is a required field. Please enter it below.<br />";
}
include 'error_reg.htm'; 
exit(); 
}

Actually its quite straightforward, in your echo, just add/wrap the html tag you desire on that message. The styling can be just as anything as you want it to look. And the placement of that error is also entirely up to you.

Here is a super basic example:

<!-- or just use an external css file -->
<style type="text/css">
.error-box {
    color:#555;
    font-family:Tahoma,Geneva,Arial,sans-serif;font-size:11px;
    padding:10px 10px 10px 36px;
    margin:10px;
    background-color: #ffecec;
    border:1px solid #f5aca6;
    width: 300px;

}
</style>
<?php
$first_name = '';
if(!$first_name){
    echo "<div class='error-box'>First Name is a required field. Please enter it below.</div>";
}
?>
