How To Show Different Banner Images on Mobile and Desktop in Shopify Trade Them

Using different banner images for mobile and desktop improves your online store in multiple ways:

• Faster Loading Speeds ⚡ – Mobile-optimized images reduce page load times.

Step 1: Backup Your Theme Before Making Changes 💾

Before editing your Trade theme code, it’s always a good idea to:

This prevents your live site from breaking if something goes wrong.
