Excellent! It worked great (after some experimentation looking for which elements I needed to target, and discovering there was extra spacing in the footer). Here’s my code for anybody else that might need it. Tom, I’m sure you have some feedback on it as well, just in case I targeted anything unnecessary. FYI, all of the feedback you have given me is easily worth the price I paid for GP premium 🙂
@media screen and (max-width: 768px) {
.separate-containers .inside-article, .separate-containers .comments-area,
.separate-containers .page-header, .separate-containers .paging-navigation,
.one-container .site-content, .separate-containers .widget.inner-padding {
padding-left: 25px;
padding-right: 25px;
}
.separate-containers .site.footer-widgets {
padding-left: 0;
}
}
