title: How to create this Popup form in ASP.Net using JavaScript?
body: <p>I'm working with a web site in <code>ASP.NET</code> for the practice and I want to make the popup form like <a href="http://beemp3.com/" rel="nofollow">beemp3</a>. When we click on <code>Playlist Login</code> or <code>Playlist SignUp</code> a popup form comes on with transparent background but we can't access the controls on the page given behind.<br>
  I'm not much familiar with the <code>JavaScript</code> or other scripting languages. My teacher told me that they are using <code>JQuery</code> to creating this popup menu but I know little bit <code>JavaScript</code> so I want to know that how can I accomplish this task using <code>JavaScript</code>.</p>
