Hi there. The accepted answer didn't work for me, so I made some tweaks.
This updated multicolumn.liquid section works well for my Shopify Dawn theme:
{{ 'section-multicolumn.css' | asset_url | stylesheet_tag }}

padding-top: {{ section.settings.padding_top | times: 0.75 | round: 0 }}px;
padding-bottom: {{ section.settings.padding_bottom | times: 0.75 | round: 0 }}px;
}
@media screen and (min-width: 750px) {
.section-{{ section.id }}-padding {
padding-top: {{ section.settings.padding_top }}px;
padding-bottom: {{ section.settings.padding_bottom }}px;
}
