Price AND ‘Add to cart’ align don’t work on OceanWP

Hi everyone!

I want ‘Add to cart’ buttons to be on the same horizontal line AND all prices to be on the same line. This page shows CSS for this: https://www.grahamethomson.com/2018/09/05/align-woocommerce-add-to-cart-buttons/
I want the second alternative (both Price AND ‘Add to cart’).

It works on most themes but not on OceanWP. Here I’ve set up a demo:

Why doesn’t it work on OceanWP? Any solutions?
THANKS for any help ?? ??

Best regards,
