In the past I have cut and pasted code like that below into the "Page Header Injection Code" for individual pages, but this time it is not working. Any ideas? Am I missing something?
.ProductItem-relatedProducts .product-mark.sold-out {
visibility: hidden;
font-size:0;
}
.ProductItem-relatedProducts .product-mark.sold-out:after {
visibility: visible;
content: 'Coming Soon';
font-size: 18px;
}
