I am working off of a fluid grid that will adapt down to a mobile screen.
The page includes small thumbnail images that when clicked, pull up a lightbox pop up of the image.
The problem is my lightbox coding seems to only allow for pixel widths (not % width or max width) and the image it pulls up would also need to someone fit to a set % or max width.
Otherwise the lightbox pop up will not properly fit into the screen.

Is anyone familiar with a type of lightbox which will accommodate this?
