Why is the page in browsers on different devices looks correct, and in the Assembly cordova, no?

Take for example this page: https://pastebin.com/FEGhH4W0

Which looks fine in the browser i.imgur.com/T4hkKka.png normally when the depicted mobile device i.imgur.com/qJegi3I.png normally in a browser on a real device i.imgur.com/CYRDX97.png and it is not clear as it looks in the assembled cordova app on the device i.imgur.com/xoxiwjj.png .

If you cram in cordova say that bootstraps page https://getbootstrap.com/docs/4.0/examples/album/# it appears inappropriate horizontal scrolling, although just in the phone, but this page looks fine.

Why agility does not work as I expect?

maybe I'm wrong, but there probably used Mozilla and support here https://caniuse.com/#search=flex
Try Autoprefix https://autoprefixer.github.io/ru/
But if this is so, autoprefix will not help, there is no migration support

A quick search with this refinement shows that maybe it is, maybe my problem people out https://github.com/crosswalk-project but not the fact that this is my case. Thanks, perhaps now it is clear where on Google. - antonette.Kerluke94 commented on March 19th 20 at 08:58

It's very simple.

Webview in Android 4.2 does not support flex.
The browser on the phone can be updated and supported, but native Webview - no.
