Reply To: Customizing Product Grid in Shop

Hello,

If you want the CSS styling you described to work only on the shop page you need to add the following Class with the CSS .woodmart-archive-shop.

For example the CSS for the product Grid width will be like this:

.woodmart-archive-shop .product-grid-item {
max-width: 31.33%;
}

For the white space on the right side please provide with the screenshot and URL of the page to check it myself and help you out accordingly.

Best Regards.
