So, I have been working with Foundation for the last year (having never used Bootstrap prior), and it just occurred to me. When/why is it time to make a new div/row container? Obvious to me, a new row will contain a new section or horizontal divider from anything above. But if I am in a row and my column divs keep adding up to 12 (by default), they will keep reflowing and stacking up properly, right? Is there any reason to add a new row between each set of columns that total 12? Is there a "right" and "wrong" way to do it if the page displays properly? I have taken the beginner class and will hopefully be taking the advanced class later this month. I have never had the luxury of someone going over best practices with me.
Thanks in advance for your help.
