How to remove the initial zoom on mobile devices?

Question

HTML

In the process of adapting the site for mobile devices, I encountered the following problem: the standard Android browser and the iOS browser display the page with the initial zoom, as a result, the page has to be reduced, but this affects the width of the elements. There is no problem in mobile Chrome and Firefox.
Attempts to fix the problem with help were unsuccessful.
Are there other options to overcome this?

Answer 1

Use the viewport meta tag like so:

<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">

Answer 2

Viewport tag to help you frontender.com.ua/mobile-web/wtf-viewport

Answer 3

Yes, the viewport tag was not displayed in the question, in fact, they tried to deal with it, but the feeling that browsers simply ignore it.
