The reason for the appearance of horizontal scrolling on a 240x320 screen?

Question

css

I made an adaptively simple page: del
On a 240x320 mobile screen (Android), the page moves to the right / left by a few pixels. That is, as if horizontal scrolling appears.
What could be the reason? There is no fixed width anywhere, everything is ok on other screens.

Answer 1

Sometimes it happens. It's because of the padding of the 100% width boxes (or the content in them) or those... Look for these boxes and play with their margins.

Answer 2

Somewhere the width of the element got out: in firefox, open web-developer->outline->outline block level elements
The borders of the elements will appear, and you will find the one that has crawled out of the screen, you can reduce it.

Answer 3

Most likely it depends on the system settings for the browser, or the web view settings in the application (if the page is opened in the application).
