A Shopify store owner encountered an issue where submit buttons on the Parcel Panel tracking app appeared blacked out, making the text invisible.
Problem: The submit boxes on the order tracking page had black text on a dark background, rendering them unreadable.
Solutions Provided:
Multiple users offered CSS fixes with slight variations:
Option 1: Add CSS code to the base.css file targeting specific button classes
Option 2: Insert CSS code in theme.liquid file above the </head> tag using {% style %} tags
Option 3: Similar approach targeting .pp_tracking_button button class
All solutions use color: #fff !important; to force white text color on the buttons.
Resolution: The issue was successfully resolved after the store owner implemented one of the suggested CSS fixes. The problem stemmed from a styling conflict between the Parcel Panel app and the store’s theme.
