Hi Bass and thanks for the prompt response.
I am using the customizr theme out of the box.
The site you provided: https://demo.jbst.eu/shop/ is fine on the list page, however, the cart and checkout pages leave a lot to be desired from a usability perspective, as is the case on my test site:
Shop (each item is pushed to a row)
https://www.rodandlineireland.co.uk/shop/
Checkout (fine full width, is not fluid on narrow screen)
https://www.rodandlineireland.co.uk/checkout/
It’s probably just a class on each item col, I may get a chance to fiddle with the css this weekend and will tell you my results if you don’t get a look first.
Thanks for your assistance.
Fiontan
