The 1140 grid fits perfectly into a 1280 monitor. On smaller monitors it becomes fluid and adapts to the width of the browser. Beyond a certain point it uses media queries to serve up a mobile version, which essentially stacks all the columns on top of each other so the flow of information still makes sense.
