Introduction
 
jQuery modal popup is very familiar and popular modal popup used in client side  script. I will show you how to change header color of modal popup and how to apply  overlay effect (background blur effect).
 
 The following is the CSS code:
 
- < style >   
 -     .info.ui - widget - header {  
 -         background: #3c8dbc;color:# fff;  
 -         font - family: Calibri;  
 -     }  
 -     .ui - widget - overlay {  
 -         position: absolute;  
 -         top: 0;  
 -         left: 0;  
 -         width: 100 % ;  
 -         height: 200 % ;  
 -     }  
 - < /style>  
 
 Here's the HTML Code:
 - <div id="DivToDisplayModelPopup" title="Upload Documents" style="display: none;">   
 
 Here's the  jQuery code:
 - var div = $("#DivToDisplayModelPopup");  
 - div.dialog({  
 -     modal: true,  
 -     width: 750,  
 -     height: 350,  
 -     resizable: false,  
 -     dialogClass: 'info'  
 - });  
 
 I hope this would help developers & beginners. So start using and enjoy coding.
