I essentially brand new to the Liquid engine. However, I program in several languages so I figure I can conquer Liquid with a few pointers.
I want my collection page to layout products like they are laid out here: http://www.boombycindyjoseph.com/pages/store
It's a 3 column layout with an Product Image on the left, Product Video in the Middle, and Text + Add to Cart on the right. I won't have a video for every product so I'll need to have some form of default placeholder in the middle.
Note that the Product Image is not the same as the Product Image in the Product Page. While optional, this would also be nice.
My Googling just led to simple answers like how to add a video to your product page.
So I could use a little help on where to start editing this. My guess is that it would be in either the collections-template.liquid, collections-grid-item.liquid, or collections-grid-collage.liquid files.
From there, do I need to add my Product Image and Product Video for the Collection Page to the Asset list or (better) somehow add a couple of fields to the product.liquid file that allows me to enter them when I have them.
