Changes between Version 1 and Version 2 of Ticket #28883, comment 19

v1	v2
3	3	I've looked at the gist of it, and was able to get to what I think is a decent handling in attachment:28883.7.diff. But as you can see in the last screenshot of https://cloudup.com/cN4DcBMqDi5, I've noticed that our banner handling is sketchy at smaller width (but tall) because we decide to switch to the other mode based on the screen height.

5		attachment:28883.7-widthonly.diff is the same as 28883.7.diff, but by detecting small-screen mode based on screen width ~~height~~<771px, like the rest, not height<500px. Any narrow screen can benefit from the smaller banner. This could also be its own ticket, but I figured I'd give you the option to do either.
