Hello,

It can be changed with the help of the custom CSS code. Paste the below code to the “Global Custom CSS” area in Theme Settings -> Custom CSS.

.product-grid-item .wd-add-cart-icon>a:before {
    content: '\f218';
    font-family: "Font Awesome 5 Free";
    font-weight: 900;
}

You will be able to set another icon by replacing the value after the slash ‘/’ of the “content” attribute using the Font Awesome service.

If there’s anything else we can do, please get in touch.
