This is what I see:

Can you provide more info about the browser? We should probably test it in different browsers and identify the ones that are affected. Needs reproduction?

Android 6.0.1
Chrome 56.0.2924.87

@bmansurov - try it on your phone, it looks aligned for me on desktop

Change 339629 had a related patch set uploaded (by Bmansurov):

@bmansurov
Chrome: new header + notifications appearing

Opera mini beta mode - non-beta header appears
expected behavior: beta mode header should appear

@Nirzar - it seems I was logged in to firefox as two different users. For the new header, is the empty bell icon expected behavior for user with no notifications?

I'm sorry to be a pain but I've also spent time and the best solution I could find that wouldn't change the HTML is center using flexbox. I've submitted https://gerrit.wikimedia.org/r/340308 as an alternative to Baha's patch.

T158957#3061586 and T158957#3060917 contain local QA on several browsers and the different tradeoffs on the solutions. I don't mind which one to choose right now, but we should do something.

Looks pretty good on Staging. Here are the screenshots:

Screenshots	Android Device OS - Browser Version	iOS Device OS - Browser Version
	Nexus 6P Android 7 - Firefox 50	iPhone 6 iOS 8.1 - Safari 8.0
	Galaxy Note 3 Android 4.4 - Firefox 50	iPhone 6S+ iOS 9.0 - Chrome 47
	Nexus 9 Tablet Android 6.0 - Chrome 55	iPad Air 2 iOS 9.0 - Safari 9.0
	Galaxy S6 Android 5.0 - Android Browser 5.0	iPhone 5s iOS 7.0 - Safari 7.0
	Nexus 6 Android 5 - Maxthon 4.5	iPhone 6s iOS 9.0 - Chrome 47

@ABorbaWMF, @Nirzar - the iPhone 5s iOS 7.0 - Safari 7.0 combination still seems a bit misaligned to me.

Summary of tradeoffs:

• Table-cell approach (Baha): All well aligned but Chrome mobile (aligned but a bit misplaced to the top)
• Flexbox approach: All well aligned but iOS <= 8 (aligned but a bit misplaced to the bottom)

The patch deployed is the Flexbox approach, which is why you see old iOS a bit misaligned.

True, it's 1-2px down.

@Jhernandez - not perfect, but I think it's okay. @Nirzar?

okay from my side

For the record, the Flexbox approach was chosen.
