With reference to a random product, http://vivreactivewear.com/shop/tops/vivid-active-tank/ ,
I would like to know if there’s any CSS that can be done to cross out (1 red line diagonally across) the size box if that variant is out of stock (with reference to the attachment)?
Thanks for writing in! I understand what you are looking for but it’s not possible. It’s because there is no associated class or something that can say it’s out of stock rather it will return the availability after selecting the options.
