Hmmm, I don't believe I changed the CSS in a way that affects the button positioning in my recent CL. 

It's more likely that this was something that I didn't pick up in this CL submitted a few weeks ago which simplified the media queries a lot: https://codereview.chromium.org/2788323002/

The media queries will need adjusting. There's a middling space that tablets and smaller desktop screens both occupy.

If someone wants to take a look before I'm back it's in: 

@media (max-width: 420px) and (min-height: 401px) and (min-width: 240px), (max-height: 736px) and (min-height: 240px) and (min-width: 421px)

body .nav-wrapper {} 

I took a quick look on Friday and came to the same conclusion. I think we just need to adjust the media queries. Surprised no one has complained!

I'm OOO through June 6 & didn't have time to land a fix before Friday evening. Nate, could you please handle this? We should probably get a fix merged back quickly.

Was OOO on Friday, but I'll take a look today and see how we can adjust the media queries.

Pending CL is up at https://chromium-review.googlesource.com/c/518544/, just waiting for Edward Jung to be back for UI comments.

Thanks Nate, lgtm'd your CL.

Choose desktop interstitial layout for medium views

We should choose the desktop layout over the mobile layout interstitials
for middle-sized views, since we're switching to the desktop layout too
soon.

This CL changes the threshold from height = 736px to 560px and removes
the extra margin on the details element. Together, these changes help
improve transitions between mobile and desktop:

 - We use the desktop layout for more middle view sizes, and we can
   display more of the details because we're wasting less space with
   padding
 - When we switch to mobile layout, the "Details" button is in nearly
   the same vertical spot as it would've been in desktop layout (it
   only moves 35px lower).
 - Clicking "details" in the desktop layout usually shows at least a
   tiny bit of the details on the screen. This serves as a visual cue
   that the user needs to scroll to see all the content. Otherwise, the
   "details" button looks as if it doesn't do anything.

Verified the issue on windows 10, Mac 10.12.5 and Ubuntu 14.04 using chrome beta version #60.0.3112.24 as per comment #0.

Observed that interstitial buttons are not seen at bottom of page after resizing browser window as seen in the screen shot in comment #0. Hence, the fix is working as expected.

Attaching screen cast and screen shot for reference.

Hence, adding the verified labels.

Thanks...!!
