responsive bootstrap gave me undefined gradient - html

Question

I try to make responsive part of this size with bootstrap grid. And always when I do resize of window, so there is made new gradient on right. I tried to find it in developer tools what it is, but there is nothing defined. I'm not sure but I have on more site with same design without bootstrap and there it looks nice when I resize window, but here with bootstrap it's bad. I am not sure if it's really bootstrap but looking for solution, because I really don't have idea.
Here is code and screen how it looks

Answer 1

You have several mistakes in your snippet.
First off, you're supposed to load bootstrap(.min).js after jQuery. You also need popper.js for v4.x.
Secondly, you should never have a .container inside another .container.
Third, you want to keep your .menu-deti from oversizing <body>, using:
.title-deti {
max-width: 100vw;
overflow: hidden;
}
