I am using the minimal theme and I would like to add a return button on the product page. It is even possible?
Go to the Online store > Theme > Sections > product-template.liquid file and add following code where you want to add Back button.
This is a very easy and lazy solution. If people come on your webpage trough Google and you press something like "Back to shop" then nothing will happen, or atleast they wont be returned to the shopping page.
