How to automatically calculate margin-left so that when resized it would give the same distance as in Bootstrap container?

Question

css

The bottom line is that there is a site on the bootstrap grid, and I need to make a block that will not lie in the grid, but it must be centered exclusively on the grid, on the left side. Maybe someone came across how to calculate a similar thing, so that when resizing it would always fall into this distance?

Answer 1

margin-left: calc(50vw - #{ширина контейнера / 2})
Of course, this is necessary for all breakpoints.
