Images change size on mobile

Site URL: https://www.iamjustinsinger.com/

A few images on my site change size and position on mobile. 

This code works for one page on my site but I'd like to apply it to all logos on all pages. Is this possible?

/* 3 logos side by side */
@media screen and (max-width:767px) {
div#page-section-5ffca32b81fa8740e19dcdbd>.row>.span-4 {
    width: 33.33% !important;
    float: left !important;
}
}

Replace #page-section-.... on each page
