title: Simple modal div in jQuery?
body: <p>I have tried almost all of the jQuery Modal plugins I can find on the net but they are all much to bulky for what I need.  I don't need all the fancy features, I want to be able to open a div and have the background of the page go transparent grey like the photo below and have my div be on top of it, that is all I need to do so I would like to write some jQuery to do this instead of using a bulky plugin.  Does anyone have any small code that can do this task?  Is the transparent background an image or just CSS?</p>
