Store Design

Topic summary

Changing the border color of the quantity field in the cart drawer on a Shopify store.

Latest updates:

  • One helper requested the store URL to inspect the theme and identify the correct CSS selector.
  • Another provided a workflow: Shopify Admin → Online Store → Theme → Edit code → open theme.liquid and insert custom CSS before the tag. However, the actual CSS snippet was not included in the post (the code block appears empty).

Key details:

  • “theme.liquid” is the main layout file for a Shopify theme.
  • The change likely requires adding CSS (Cascading Style Sheets) targeting the quantity input in the cart drawer (slide-out mini cart).

Status:

  • No confirmed solution yet; guidance is incomplete due to the missing CSS code.

Action items / next steps:

  • Provide the store URL so helpers can check the live theme and advise the exact selector.
  • Share theme name/version.
  • Post or request the specific CSS needed to change the quantity input border color.

Open questions:

  • Exact CSS selector and style rules to apply remain unspecified.
