when I design a map for use on a desktop PC, I typically use a landscape format with
Code: Select all
width: 100%;
I choose a zoom factor to get everything necessary into the map.

When this map is displayed on a smartphone, it will not completely fit into the screen; you won't see important things on the right and left sides.

Of course the user can zoom the image, but there might be a better solution: Why not ask for two zoom factors during the map definition, one for desktop, another one for mobile?
