Debut theme - adding alt tags to collection

Store Design
1

Hi…wondered if anyone can help. (using the Debut theme)
Two things really (although associated)

  1. I’m trying to add alt tags to the collection-grid-item on the collections page and on featured collections on the homepage
  2. the changes I’ve tried don’t appear to be updating the live site.

I’ve figured it out…if anyone else needs this…I added
alt=“{{ product.featured_image.alt }}”

to line 2 of product-card-grid.liquid
