Join Justin Schwartzenberger for an in-depth discussion in this video Attribute directives: built in, part of Angular Essential Training (2018).
- [Instructor] Attribute directives are designed…to change the appearance or behavior of the DOM elements…that they are attached to.…They do not create or remove DOM elements…like structural directives.…Let's take a look…at how you can use a built-in attribute directive.…In the media-item-list.component.html file…we will make use of the ng class, attribute directive…to get some CSS classes onto the mediaItem elements…based on the mediaItem medium type.…
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,…
