Problems with mobile

How to make Lightbox Plus Colorbox responsive?
on mobile devices a lightbox is rendered unusable, it is too small (covering 30% of the small mobile screen) and non-resizable. How to make it responsive and show on full or at least 90% of the mobile screen area?

Please open this example using any mobile device and click on any state to open lightbox.
