How to customize the product image border frame in Dawn theme?

Topic summary

A user seeks to customize the product image border in Shopify’s Dawn theme. While the theme includes a ‘Show image border’ option under Featured Collection settings, the default border is too subtle.

Solution Provided:

A community member shares CSS code to customize border color and weight:

  • Add code to component-card.css (Online Store → Theme → Edit Code → Assets)
  • First code snippet targets product grid borders on homepage
  • Second code snippet (product__media-list .product__modal-opener) addresses individual product page borders

Current Issue:

The CSS modifications work on desktop view but fail to display on mobile devices. The original poster lacks a live store URL for further troubleshooting since they’re testing the theme.

Additional Question:

Another user asks about code placement within the component-card.css file, having tried both beginning and end positions without success in seeing borders.

The discussion remains open with unresolved mobile responsiveness and implementation questions.

Sorry, I don’t have a URL as it isn’t a live store yet.
