How do I completely REMOVE the quantity option for add to cart button?

Hiya.

I'm looking to add 6 different product blocks on my music page -  I will remove all options from visibly so that I am just left with an "add to cart button". How can I now remove the "quantity" option? Removing "the add quantity" option can remain site-wide for now... no need to target each product block. I just want a simple "add to cart."

Thanks in advance!

This should help, add to Custom CSS

.product-quantity-input {
    display:none;
 }

WORKED GREAT! THANKS!
