I am looking to add a strikethrough to out of stock variants on the collection page. Any ideas?

[Sheehan]

When a customer is on the product page, the variants that are out-of-stock have a strikethrough. When they are on the collection page, the out-of-stock variants do not have a strikethrough. I do not want people wasting their time clicking into a product page only to find what they were looking at is out-of-stock. How do I add a strikethrough to out-of-stock variants on collection pages and anywhere else the product appears outside of the product page? Thanks. I am using Beyond theme 3.4.3. Here is a link to the collection page
