Good article, but rule #7 shows a snapshot animation that break rule #2 above it. In rule #7 the animation shows a form with two fields next to each other, wheras rule #2 says do not place input fields next to each other. On the animation under rule #7, it’s even confusing how does “Specific Location” relates to the price it is located next to. That price is available at that specific location? But in that case that would be important to know and not optional (I might have to pay 100 bucks more at another location). Anyhow, sorry, just nitpicking :-) Good tips, though!
