This guide explains how to display a product’s size (like 750ml) under the product title.

Step-by-Step Guide
Step 1: Open the product.
- In Shopify Admin → Products, open the product you want to edit.
Step 2: Add a Size variant.
- Under Options, add an option named Size (case-sensitive).
- Add your size values (e.g.,
750ml,1L, etc.).
- Click Save.

Step 3: Enable size on the theme.
- Go to Online Store → Themes → Customize.
- Open the section that controls your product cards (e.g., Product list).

Notes
- The option name must be exactly Size for the theme to detect it.
