Reply To: How to delete or hide only the first line of the “clase” attribute

Hello,

Please try to use the below custom CSS code and paste it to Theme Settings >> Custom CSS >> Global CSS section:

.single-product .wd-before-add-to-cart, .wd-after-add-to-cart {
    display: none;
}

.summary-inner.set-mb-l.reset-last-child table.woocommerce-product-attributes tbody td {
    font-size: 20px;
    font-weight: bold;    
}

Best Regards.
