Hello!
I can not understand why when you change the scale of the site, it starts to collapse!
I wrote the site about 2 months ago and only now I noticed an error. Made up through the grid jeet/

Answer 1

@media only screen and (max-width: 991px) and (min-width: 768px)
_grid-sm-min-an…sm-max.scss:65
.mod-2 {
    overflow: hidden;
display: none;

Answer 2

Because all styles work for you up to 1920 pixels of the window width, everything that is larger than this window (just at 75% scale) does not use styles anymore.
