You can set as many breakpoints as you need, there is no limit. Responsive breakpoints are defined on Sizes tab. Go to this tab, and press Add Breakpoint. After that specify the window width you need in pixels, set the number of rows and columns that you need, and the gutter value. The responsive breakpoints option is very flexible, so you can set several breakpoints for any screen size, just don’t forget to save the changes you have made. However, here are our recommendations for optimum kinds of breakpoints:
- 1024 (for tablets with landscape orientation) for 3 or 4 columns at best;
- 768 (for tablets with portrait orientation) for you 2 or 3 columns at best;
- 480 (for mobile phones) for 1 or 2 columns at best.
