Hi,

I just wondered if there was code I could input to reduce the spacing in between the headers 'product description' and 'additional info'.

And if there was a way to move this copy underneath the button.

Thanks!

Hi. Add to Design > Custom CSS

section.product-details.ProductItem-details {
    padding-top: 0px;
}
nav.ProductItem-nav {
    display: none;
}
