popup after contact form submit we want the "message sent" message that comes out after you submit the sitewide contact form to come out in a popup instead of in a div on the front page.  How can I achieve that?

I have googled everywhere and asked questions on drupal.org but no one has answered me.
You can use Better Messages module


  Better Messages is a very simple module that provides "Popup-like"
  Drupal messages.
  
  Better Messages intends to let you control where and how you want to
  see your Drupal messages! Combine different animations and override
  better_messages.tpl.php to create your custom look.
