When using mobile or tablet devices, have you encountered any usability or technical problems with Lightbox overlays? Any navigation problems?
I frequently see these two problems with overlays on my iPhone:
1. Close buttons that are way too small. I shouldn't have to zoom in on the close button just to see and press it. If you don't want big close buttons on the normal website, do a media query in the CSS to use a larger button/icon on mobile devices.
2. Overlays that aren't properly positioned within the viewport, especially when you are zoomed in on the page. I'm not sure what causes this, but I would guess that it's related to the overlay being a fixed size that's too big for the viewable area.
