Hi,
This is not supported primarily because there are so many different mobile platforms (and new ones popping up each day). Unfortunately, maintaining the platform-specific code for each mobile platform would not be practical.
Another option would be to optimize the display of items in the lightbox using a responsive theme. The default themes in SLB 2.0 will be fully responsive and theme designers are encouraged to add responsive functionality to their themes as well.
I am building a responsive theme, but the simple lightbox expands to be too large on a mobile screen. Thanks.
Are you referring to a responsive theme for WordPress or for Simple Lightbox (SLB)?
SLB themes are independent from WP themes but they can also be made to be responsive, thus keeping the lightbox from expanding too large on mobile devices.
