I was wondering whether it is possible to alter the dimensions of the pop-up boxes that appear in maps. I've looked at the configuration options, but these all seem to relate to material inside the pop-up, not the frame. Is it possible to alter this anywhere else e.g. in the CSS or in the code in JSON?
I ask because in the pop-ups I have a thumbnail and various fields, and at present the pop-up is just too small and necessitates scrolling, something I'd rather avoid from an accessibility point of view.
Thanks
