title: Remove class after 3 seconds
body: <p>I'd like to put a timeout function to remove these two classes, but I have no idea how to do that. Can anyone help me how to include a timeout here? Thanks in advance. </p>
  
  <pre><code>.done(function(response) {
              // Make sure that the formMessages div has the 'success' class.
              $(formMessages).removeClass('error');
              $(formMessages).addClass('success');
  
              // Set the message text.
              $(formMessages).text('Message sent!');
  
              // Clear the form.
              $('#name').val('');
              $('#email').val('');
              $('#message').val('');
              //$('#budget').val('');
          })
