The Cart Items element is not too customizable, for example it doesn’t allow for customizing the quantity plus/minus button styles. It’d be great if we could add further customization to it. Another example is that the Products options don’t appear to be settable by breakpoint (i.e. I cannot easily disable product images on lower breakpoints while keeping it on desktop only).
For anyone looking to put a different colour in for the plus & minus action buttons for the quantity, I found the CSS below to work well:
.woocommerce-cart-form .product-quantity .quantity .action
{
background-color: var(--bricks-color-chijcl);
}
