Part of the options of a jewelry site I'm making allow you to build your own pieces based on a bunch of options and criteria. Since not all of them will have images, and it's hard to tell what they are out of context, I want to have a link to a small pop-up that will host an explanation. Where would I need to add this link in the override system?

While the ideal scenario would be for each option to have its own pop-up, I think linking them all to 1 "all-encompassing" page will have to do.

(A) Where would I add the link in the markup?

(B) Is there a preferred way to create a small pop-up page?

There's an attachment in this thread that shows what I'm talking about
