How do I put blocks side-by-side on mobile using CSS?

This is how it looks on a desktop version, how would I go about making two images at a time to show? Also is it possible to make the "Some of Our Recent Customers" to display at the beginning rather than the middle.

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
div#block-yui_3_17_2_1_1595186156795_77770+.row>.col {
    width: 50% !important;
    float: left !important;
}
div#block-yui_3_17_2_1_1595191726115_37578+.row>.col {
    width: 50% !important;
    float: left !important;
}
div#page-section-5f149bf940592a3871aa45ab .span-12>.row:nth-child(4)>.col {
    width: 50% !important;
    float: left !important;
}
}

Thank you so much! Quick question, how do you identify the page section?
