Looking for a plugin for a popup

I am trying to do what this site does. At the bottom of the page is a Quick Answers popup. I am looking for a plugin that will accomplish this. Is there a particular name for this type of popup? I have been searching the plugins and haven’t found what I needed yet.

Here is the example I want to try to mimick.
