How to remove site shift when scrollbar appears?

Question

css

When a stripe appears, the site shifts to the left by a few pixels. How to remove this effect? So that, regardless of the presence / absence of a strip, the site is always in 1st place.
I found a lot of articles, but they are all quite old, is there already a more elegant way?
Without JS preferably)

Answer 1

The layout should be correct, adaptive and initially not under 1920 pixels, but under 1900, taking into account that the scrollbar takes 20 pixels.

Answer 2

There are different browsers. Everyone has different stripes, wide, narrow. Even in the same chrome, the old ones have a stripe, while the new ones do not take up a single pixel. To solve the problem, the site must be rubber.
