CSS issues on narrow (e.g. tablet) screens

[dumblob]

When using a narrower screen (e.g. a tablet), items in tables (e.g. on the "sprava rychlych kontaktu" view) become so narrow, that one can't even see them after clicking/touching them as they get completely overlapped by an icon (e.g. to save the changes).

I don't see any major issues on my tablet or phone.
Which OS/browser are you using and what's the screen resolution?

after double clicking/tapping "Nazev"

after double clicking "Cislo":

I'm testing in Chromium. An example tested resolution is 1680x1050 with 125% "whole page" (not just text) zoom.
