How to remove white stripes on the right in the mobile version of the site?

Good day, engaged in the development of the website . The problem is that in mobile version on the right has a white stripe and remove it is simply impossible, tried a bunch of method (viewport, overflow, margin, width 100%, max-width 100%), many people even from this forum and nothing helps. I would greatly appreciate for the help))

The case in this property:
@media (max-width: 991px)
.video-gradient-background {
 position: absolute;
 width: 120%;
 height: 70%;
 margin-left: -10%;
 background-color: #6f011c;
 margin-top: 6%;

Change the width to 100% instead of 120
where did you get this, I can't find it in the style file))) - elta.Denesik commented on June 5th 19 at 21:54
