JQueryUI - Day 9 (Dialog)

Before reading this article, I highly recommend reading the previous part of the series:

jQuery Dialog opens content in an interactive overlay. Dialog boxes are one of the nicest ways of presenting information on an HTML page. We can define dialog as a floating window with a title and content that can be moved in any direction or may be resized.

Syntax:

$(selector, context).dialog(options);

Or

$(selector, context).dialog("action", [params]);

Example:

  1. <!DOCTYPEhtml>  
  2.   
  3. <head runat="server">  
  4.   
  5.     <title></title>  
  6.
