Angular is a platform for building mobile and desktop web applications. Join the community of millions of developers who build compelling user interfaces with Angular.

On this page we will provide angular 2 NgClass example. It is used to add and remove CSS classes on an HTML element. We can bind several CSS classes to NgClass simultaneously that can be added or removed. There are different ways to bind CSS classes to.
