2 products across on mobile shop

I am looking for a way to display 2 items across when people are shopping my site on their phones. Any help would be greatly appreciated!

Add to Design > Custom CSS

@media screen and (max-width:767px) {
.products.collection-content-wrapper .list-grid {
    display: grid;
    grid-template-columns: repeat(2,1fr);
    grid-gap: 10px 10px;
}
}
