You can edit this stylesheet code to improve the appearance of the form elements.

Jquery Code

code is included inside the js/script.js file

	$(document).ready(function(){
		/* Show Feedback form when feedback button clicked */
		$('#feedback_button a').click(function(){
			$('#feedback_overlay_box').show();
		});
		/* Hide Feedback form when close button clicked */
		$('#feedback_close a').click(function(){
			$('#feedback_overlay_box').hide();
		});
		
		/* Following code will be called when user submit the feedback form */
		$('.wp_feedback_form').submit(function(){
		var url = $(this).attr('action');
		var update = url.split("#")[1];
		var name = $("#feedback_name").val();
		var email = $("#feedback_email").val();
		var website=$("#feedback_website").val();
		var message=$("#feedback_message").val();
		var dataString = 'email='+ email + '&name=' + name+'&website='+website+'&message='+message; 
		var emailFormat = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;

		/* In first part of this code we validated inputs entered by user. */
		if (email == '' || name == '' || website=='') {
			$("#feedback_error").fadeIn(200).html("All fields are required !");
		}else if (email.search(emailFormat) == -1) {
			$("#feedback_error").fadeIn(200).html("Invalid Email Address!");
		}

		else
		{
			/*
			Following code will send a jquery ajax request to the send_email.php file,
			with user inputs */
			$.ajax({
				type: "POST",
				url: "" + url + "",
				data: dataString,
				success: function(response){
			/* Response is add to the #feedback_response div */		
					$('#feedback_response').html(response);
					
				},
				complete: function(){
			/* On completion of ajax request following methods are called. */
					$("#feedback_error").fadeOut(200);
					$("#feedback_response").fadeIn(200);
					$(".feedback_text").val('');
					}
				
			});

		}
		return false;
		});
	});

PHP CODE

For email sending we will use php mail()

 <?php
	$to="mail@website.com"; /* All the emails will be sent to this email address. */
	/* Get all the field values */
	$from=$_POST['email'];
	$name=$_POST['name'];
	$website=$_POST['website'];

	$subject="Feedback Posted on  Your Website"; /* Subject added to email.*/
	$success_message="Thanks For your feedback!."; /* Success message displayed on the form.*/
	$info =addslashes($_POST['message']); 
	$message="<h2>".$subject."</h2>";
	$message.="<p>Name = ".$name.'</p>';
	$message.="<p>Email = ".$from.'</p>';
	$message.="<p>Website = ".$website.'</p>';
	$message.="<p>Message = ".$info.'</p>';
	// To send HTML mail, the Content-type header must be set
	$headers  = 'MIME-Version: 1.0' . "\r\n";
	$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
	$headers .= 'From:'.$from;
	if (mail($to, $subject, $message,$headers)) {	
	echo $success_message;	
	}
	else
	{
		echo 'ERROR Sending Email. Please try again.';		
	}

 ?>
