If you are talking about: http://cs12jkk.icsnewmedia.net/RestaurantApplication/register.php If you look at the html source you will see the html is all there. The problem is with line 5:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="register.js">
You don't have a closing />
or a </script>
after you include register.js
so all of the html after that isn't being rendered because it assumes it is part of your <script>
.
