// validate contact form

            },
            answer: {
                required: true,
                answercheck: true
            }
        },
        messages: {

            message: {

                minlength: "thats all? really?"
            },
            answer: {

            $(form).ajaxSubmit({
                type:"POST",
                data: $(form).serialize(),
                url:"process.php",

                    $('#contact :input').attr('disabled', 'disabled');
                    $('#contact').fadeTo( "slow", 0.15, function() {
                        $(this).find(':input').attr('disabled', 'disabled');
                        $(this).find('label').css('cursor','default');
                        $('#success').fadeIn();
                    });
                },
                error: function() {
                    $('#contact').fadeTo( "slow", 0.15, function() {
                        $('#error').fadeIn();
                    });
                }
            });
        }
    });
});

The CSS has a flaw. One must declare the font-size in px before the font-size in rem. This way only Internet Explorer will use the font-size in px (because Internet Explorer doesn't understand rem), but all the other decent browsers will use the font-size in rem.

This is not working for me!

I have the same challenge with my HTML to PHP contact form
HTML is as follows:
!DOCTYPE html>

<title></title>

		<form action="form_process.php" method="post">

	        <div class="form-group">
	          <input type="text" class="form-control" id="name" name="name" placeholder="Name" autofocus size="20" value="" required/>
			  <div class="help-block with-errors"></div>
	        </div>
	    
	    
	        <div class="form-group form_left">
	          <input type="text" class="form-control" id="email" name="email" placeholder="Email" size="20" value="" required/>
			  <div class="help-block with-errors"></div>
	        </div>
	    
	      <div class="form-group">
	           <input type="text" class="form-control" id="phone" name="phone" onkeypress="return event.charCode >= 48 && event.charCode <= 57" maxlength="10" placeholder="Mobile No." value="" required/>
			   <div class="help-block with-errors"></div>
	      </div>
	      <div class="form-group">
	      <textarea class="form-control textarea-contact" rows="5" id="comment" name="message"  placeholder="Type Your Message/Feedback here..." type="text"></textarea>
	      <br>
      	  <button class="btn btn-default btn-send"> <span class="glyphicon glyphicon-send"></span> Send </button>
	      </div>
 		</form>
 		
 		<div id="success">
		<span>
				 <p>Your message was sent succssfully! I will be in touch as soon as possible.</p>
		</span>
		</div>
		<div id="error">
		<span>
				 <p>Something went wrong, try refreshing and submitting the form again.</p>
		</span>
		</div>

<!--contacts script

   <!-- end of contacts script-->

and the contact_process.php is as follows

$value){ $message_body .= "$key: $value\n"; } $to = '[email protected]'; $subject = 'Contact Form Submit'; if (mail($to, $subject, $message)){ $success = "Message sent, thank you for contacting us!"; $name = $email = $phone = $message = $url = ''; } } } function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data; } The above cannot execute like I want it to do where it is able to send email to the user.
