Hi, I have set breakpoints at templates for mobile and tablet like this @max_col: 12; /* default breakpoint */.aem-Grid {.generate-grid(default, @max_col);} /* phone breakpoint */@media (max-width: 768px) {.aem-Grid {.generate-grid(phone, @max_col);}} /* tablet breakpoint */@media (min-width: 769px)...
