Hi

How do I make these 2 buttons which are side by side on desktop, side by side on mobile rather than stacked?

Thanks!

Please use this custom css

@media only screen and (max-width: 640px) {
    #block-yui_3_17_2_1_1606495592961_14577 + .row .col {
      width: 50% !important;
      float: left !important;
    }
}
