Can you elaborate on this a bit? Web presentation of dynamic content tends to be rectangular by nature; do you mean the "static breakpoints" responsive design style rather than the "fluid layout with breakpoints" design style?

We went the fluid route to try to accommodate as many screens/devices/orientations as possible without wasting a ton of space; a more rigid design is definitely sharper (and frankly, would be easier to produce), but we're gunning for a design that works on just about any screen size or aspect ratio, and found that rigid designs weren't cutting it.

Totally fair if you don't like, it, though. What would be the first thing you'd change?

(I don't lead design, so it's not my call; I'm just curious)
