hi there,

im wondering if someone can help me with the CSS code to change the product title font on my homepage?

also, is there a way to remove/change the quantity box?

.product-block .productDetails .product-title {
    font-family: 'book' !important;
}
.homepage .product-quantity-input {
    display: none;
}

Thank you @tuanphan that worked perfectly.
