re: is it possible to display tiles # depending of the screen size.
re: basically speaking in bootstrap terms, can i implement any classes here and how to address to tiles
There are a lot of classes available for CSS selectors. You can use the browser console to inspect them. Perhaps you can come up with a creative solution to get the result you are seeking. Of the top of my head I can not think of any to provide you some guidance, sorry.
Not certain my answer is helpful, but I do hope you do find it helpful.
