The border radius of the product card does not work

The border radius of the product card does not work. I would like a product card with a background color and a border radius. but i can’t add border radius. The border radius of the product image cannot be adjusted so that the bottom of the image is sharp and the top is round. why can’t such a simple thing be done? could wix fix this. can this be coded in css? solutions? this is a pretty big shortcoming.
