Currently, when the user clicks the cart icon on an item the icon turns blue and that’s it. No matter how many times you press it, it’s just blue. But what’s really happening is that every click is adding quantity of that item in the cart. Can there be a notification on the cart icon, the same notification icon as the main shopping cart button located at the top of the page. That button usually has a number on it that corresponds with the number of items in the cart.
