CSS Quick View

I'm editing all CSS in quick view. I managed to change the following codes:
 

.sqs-product-quick-view-content {background-color: white!important;}

.lightbox-inner .ProductItem .ProductItem-details * 
{color: #5A5A5A;}

.sqs-product-quick-view  .sqs-add-to-cart-button
{background-color: #F6F0EA}

However, I'm having issues with quantity. My background is white and quantity as well. Visitors are not able to see the input placed. I tried the following:

.sqs-product-quick-view .sqs-product-quantity-input
{color: black!important;}

WOULD LOVE SOME HELP!

Quantity in Quick View Only or Quantity in Quick View + Individual Products? If both, use this CSS

If quick view only, can you share link to shop page on your site?
