Goal: reduce the side margins (make containers nearly edge-to-edge) for the product description on mobile in Shopify’s Dawn theme. An image is provided to illustrate the wide margins.
Suggested fix: add a mobile CSS rule in assets/section-collection-list.css targeting .collection-list-wrapper.page-width to set padding: 10px and width: 100% for screens ≤749px (via a @media query).
Result: the change had no effect. The requester also tried similar edits in base.css and section-main-product.css without success.
Key terms:
Dawn theme: Shopify’s default theme.
@media (max-width: 749px): CSS that applies on mobile screen widths.
.collection-list-wrapper.page-width: the CSS selector targeted; properties changed were padding and width.
Status: unresolved. Next step needed is identifying the correct file and CSS selector controlling the product page’s mobile container/margins. The attached image is central to understanding the desired visual outcome.

How to make the containers on the sides of the product description smaller in MOBILE VERSION in Dawn Theme? They are too wide for me. I want to make it almost edge to edge, at least 50% smaller.
