Join Justin Schwartzenberger for an in-depth discussion in this video Attribute directives: built in, part of Angular 2 Essential Training.

Now the project already has CSS rules set up…in the media-item.component.css file for some classes.…So we can just start using those in the template here.…So on the mw-media-item element…we use the directive property template syntax…using the brackets around the term ngClass…and set that equal to a statement.…The ngClass directive expects an object structure…for its statement value.…
With the CSS classes for the property names…and a true false for the values.…In our case, we want to have two CSS classes.…One named medium-movies…and one named medium-series.…Since the dash is not valid in an object property,…
