Provide code for popover similar to attached screenshot (notice how the background is darker!). The goal is to capture Newsletter subscriptions.
The site it's being used on already uses jquery.min.js (1.5.1) as well as jquery-ui.min.js (1.8.4) so this is what should be used.
I want to be able to just paste the JS code into the head section on every page the popover should appear on and be set.
The JS should call a regular HTML file located elsewhere on the server (please provide sample code), which would allow easy editing of the actual code.
