It's apparently original code, so cannot be fully revealed here in the forum due to our rules respecting others' copyright.
But basically it's a div
position: fixed; bottom: 0; display: none; that's brought into view 2.4 seconds after the document is parsed via jQuery using:
Code:
$("#email-signup-bar").delay(2400).slideUp(1000).fadeIn(700);
on document.ready. It's hidden using:
Code:
$("#email-signup-bar").hide();
when you click the X button or the no thanks link. It also sets a 6 month cookie when hidden (that's with the X button, the cookie may last longer with the no thanks link). The cookie is checked to see if it's there before revealing it in the first place. There appears to be no way to get it back once you dismiss it unless you delete the cookie manually form your browser and refresh the page. It doesn't have to be like that, the person doing the site apparently chose not to have an easier way to bring it back.
There are other functions involved with processing the sign up form, and other styles as to width, height, background color, layout of the form within it, etc. There does seem to be some sort of gradient shadow along its top edge, either from a PNG image or css. That's the basic concept. If that's not enough for you to go on, when I get more time I may make up a simple demo for you.
It's very similar to:

The biggest difference being that it comes from the top.
