Fluid or fixed grid system, in responsive design, based on Twitter Bootstrap
... the confusing thing to me remain that the 'proper fixed width' example DOES change sizes of columns as browser window changes (beause it's responsive?) And so does the proper fluid width example. But I guess the fluid width example does it continuously, and the fixed width responsive example doe...
