bPopup is a lightweight jQuery modal popup plugin (only 1.34KB gzipped). It doesn't create or style your popup but provides you with all the logic like centering, modal overlay, events and more. It gives you a lot of opportunities to customize so it will fit your needs.
The iframe popup which loads a page into the popup doesn't show scrollbar, horizontal nor vertical. If the page is larger or higher than the visible part, you can't scroll the iframe content and see the right/bottom part of the page.
Bug is also visible on demo page. Into the iframe, do a search (type some word and hit enter) you get the result page but can't see the results of the search.
