Changing the picture size from vertical to horizontal on e- commerce store

Hi, does anyone know how to change the size of the picture on e- commerce store from vertical to horizontal? So the picture is in 16:9 but its displayed as a 2:3, thats the code I used but was unsuccessful with there change  

/* Adjust the image size in Quick View */
.sqs-product-quick-view .sqs-product-image img {
    max-width: 100%; /* Ensure the image doesn't exceed the container width */
    height: auto; /* Automatically adjust the image height to maintain aspect ratio */
}
 

Thanks a lot,

Patrick 

can you share your link? It's easier to come up with the code on a live page

Ok, I managed to sort it out
