Using the div divDialog for displaying the jquery UI Dialog box. Dialog window pops up and display the message. But I am not able to see the divsection divDialog in the html page at the end. Thought Jquery UI dialog code is hiding it with display:none when dialog is initialized. Tried many way to display it but nothing is working. Pasted the code below
<!DOCTYPE html>

$(function(){
        $("#divDialog").dialog({
                resizable: true,
                autoOpen:false,
                show: {
                        effect: "blind",
                        duration: 1000
                },
                hide: {
                        effect: "explode",
                        duration: 1000

                modal: true,
                width:400,
                height:300,
                buttons: {
                        ok: function() {
                                $(this).dialog('close');
                        } //end cancel button
                }//end buttons

               $("#divDialog").html("<b>test123</b>");
                $("#divDialog").dialog('option','title','Display Example');
                $('#divDialog').dialog('open');
});
