Change size + align related products

Hello, 

Wondering if someone could help... 🫣

Looking to have x5 related products on one line. 

https://laserengravingservice.co.uk/shop/p/oval-signet-rings/9ct-yellow-gold

This is the code I have created so far... 

//Change related product size - Start//

.ProductItem-relatedProducts .list-grid .grid-item:nth-child(n+6) {
    display: none;
}
.ProductItem-relatedProducts .list-grid 
{grid-template-columns: 200px 200px 200px 200px !important;
}

//Change related product size - End//

Add to Design > Custom CSS

/* Related products 5 columns */
@media screen and (min-width:992px) {
.ProductItem-relatedProducts.ProductList.clear.sqs-pinterest-products-wrapper .list-grid {
    grid-template-columns: repeat(5,1fr) !important;
}
}
