Bootstrap what will happen if I put more than 12 c

问题:

what will happen if I put more than 12 columns in a row?

Is there any explanation on this in Bootstrap docs?

回答1:

It's totally fine. It just means they will bump down to the next visual row, and space out responsively. Everything is floated left for that very purpose.

I do think the naming of .row creates some confusion, because a .row can span multiple "rows" of divs depending on your screensize and the # of divs you stack up.

No you can use like that; http://jsbin.com/gusawere/1, bootstrap 2.X had problems with that usage but 3.x dont.
