Mobile container padding

Okay Leo, I found the main issue. There was another simple-css code of line still in the post. Which line can I remove to adjust it for mobile devices?

/* remove space between nav bar and content */

@media (max-width: 768px) {
    /* CSS in here for mobile only */

.separate-containers .site-main, .entry-content {
    margin-top: 0px;
}
.separate-containers .inside-article {
    padding-top: 0px;
}
}

Should be this one:

.separate-containers .inside-article {
    padding-top: 0px;
}

Fixed, thank you.

No problem :)
