Responsive Columns

Hi staff of Tint plugin 🙂
The plugin is really great, and the services you offer is fantastic, but in a responsive theme the number of columns don’t decrease like happens in your official website, so if i set 4 columns and then navigate my website with a smartphone i see 4 tiny little columns. How can i solve this problem?
