Hello Dioniz, thanks for your reply,
I have checked here Lines from 168 to 167 :
ul.product_list.grid > li .product-container {
background: black;
padding: 0;
position: relative; }
ul.product_list.grid > li .product-container .product-image-container {
border: 1px solid #d6d4d4;
padding: 9px;
margin-bottom: 13px;
position: relative; }
@media (max-width: 767px) {
but as you can see the background is already set to black, but doesn't work.
do I have to add a line with the background color here?:
ul.product_list.grid > li .product-container .product-image-container {
thanks
