In general, I sit stupid. I tried many things, but the right decision never came to me. Most likely, everything is very simple, but alas, ah.
I am writing using the Bootstrap 4 grid. I don’t know how to position the background correctly. It should be two-color. This should extend beyond the limits of the bootstrap container. And accordingly, everything else should be in the container. How to arrange objects inside - I know. Problems with the structure of the code in html for a two-color background on a single row.
