Product List field: Make the background of all product images transparent

to make the background of all product icons look transparent (=> light green, like the page) instead of the actual white ?

Use this custom CSS code to make the product images' background colors transparent:

.image_area.form-product-image-with-options {

  background-color: #ffffff00!important;

}

.form-line[data-payment=true].form-line.card-3col .form-product-item, .form-line[data-payment=true].form-line.card-2col .form-product-item {

    background-color: #ffffff00!important;

}

Here's the result:

Wonderful, thank you ! :-)
