The net designer really did there only because I saw it in other layouts, and I thought that all we have to do logic in it. In any case, it shows you the maximum container width: 1578рх. That is asking a new breakpoint in bootstrap (+30рх padding of the container):
@media (min-width: 1650px) { .container { width: 1608px; } }
Then you distribute a uniform grid of 12 columns with padding 15рх on each side (sum of between columns 30рх) and operate .col-lg-*. After 1650рх (that is, for screens of 1600, 1440, 1366, 1200) is picked up by a standard bootstrap container 1170рх.
In principle, bootstrap to impose possible, because there are even blocks for this approach (cards for 25%, 50%, etc.).
