{{ 'section-collection-list.css' | asset_url | stylesheet_tag }}
{{ 'component-card.css' | asset_url | stylesheet_tag }}
{{ 'component-slider.css' | asset_url | stylesheet_tag }}

{%- style -%}

    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;
