Delayed popup with sticky/stretchy items?

[designer_k]

Hello,

I am trying to create a delayed popup that "grays" out the main website and has some element on top of the gray box, similar to the delayed popup email subscribe form on this website:

I have extremely limited Javascript knowledge, but I've been able to use the code I found from Acorn on this forum with his Fancy OnLoad Pop-up found on this thread:

The delay coding works, but only if the popup layer has no sticky/stretchy items. Because our main website has a sticky navigation menu, the nav bar shows on TOP of the transparent black box. This isn't the ideal design choice. If I add sticky or stretchy to any of the items, the popup never shows.

See my test site here:

Is there a way to have sticky/stretchy objects on the popup layer with the Javascript for a delayed popup load? Or is there another way to achieve this look/feature that I'm unaware of?

Thank you for any help!
