From the jquery page...
Event Handling
Show the #banner-message element that is hidden with display:none in its CSS when any button in #button-container is clicked.
Code:
1 var hiddenBox = $( "#banner-message" );
2 $( "#button-container button" ).on( "click", function( event ) {
3 hiddenBox.show();
4 });
Not sure if this has anything to do with anything. I just literally was looking at it when I read the thread.
