Adaptive layout. Mobile version. Why the white stripe?

Question

css

I'm building a website.
The template on the network was taken as a basis, then it was corrected.
For several days I have been struggling with the question - where does the white stripe come from (see picture).
None of the elements have a margin on the right, everything is in containers.
Tell me, please, what could be the reason!
Thank you in advance.

Answer 1

Some of the elements climbs out of the block. Usually text. Most likely the word "recovery". Reduce the font.

Answer 2

carousel in the results of the participants

Answer 3

code give figs so you will understand, most likely some class in css is incorrectly described.
use to describe the header
.myheader{
media (min-width:$screen-xs){
font-size: lala
}
media (min-width:$screen-sm){
font-size: lala
}
}
