Now, to begin, insert our “Add To Cart” block.
Then, explore the “Quantity” option from the right side and, for example expand the Quantity Decrease option to apply styles to it.
That’s how you can customize styles of the quantity icons for our Add To Cart block. If you still need help, please create a support ticket on our forum.
