Okay so the virtue-child/style.css is working with the code as suggested:
Theme Name: virtue Child
Description: virtue Child Theme
Tags: light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready
After deleting the a.added_to_cart properties: right
I assume that after it is deleted, it was using the woocommerce.css style which is the only other place a.added_to_cart is found.
Leaving the virtue.css as default, I added the woocommerce.css property to my child theme style.css
No response - The virtue.css property is still in tack.
So, I think it's still at square one. Is there anyway I can remove the following property from virtue.css through my child theme?
