Icons are everywhere in a website and their primary purpose of guiding and giving out information to visitors is a highly important one. Other than words themselves, these little graphics within a website that tells you how you can move to the next page, cancel a transaction, checkout the cart and the likes, basically the entire navigation. In a general sense, they act as symbols that allow easier and smoother communication between the webpage and the person interacting with it.
