I was just setting my browser to 768px wide.

But just in case I was mistaken, and both my screen calipers and chrome's width variables were somehow wrong, I set my resolution to 1280x768, then rotated the monitor. (Some graphics card drivers let you do this, others don't. The first computer I tried didn't support 768px height but supported rotation, the second I tried didn't support rotation but supported 768px height, but the third one was just right.)
