Icons are a necessity when building a website or an app. They’re used practically everywhere and for different reasons. Some designers use them for aesthetic reasons, while others use them for more practical ones. The hamburger menu icon, for example, is up to a certain point used for practical reasons, thanks to its familiarity.
There are other icons, though, that are used to beautify a website. Most websites with minimalist design make good use of icons, by enriching the layout without cluttering it.
