19.2k

  • Make a class using the @Directive attribute.
  • Assign the attribute directive name to the @Directive decorator's selector metadata.
  •  Change the appearance and behaviour of the host element by using the ElementRef class to access the DOM.

To make a custom directive, we must use the @Directive decorator instead of the @Component decorator. So, let's begin by making our first Custom Attribute directive. We'll use this directive to highlight the specified DOM element by changing its background colour. Create a highlight for your app.

  • Component is a template-based directive.
  • Structural directives - controls DOM elements, allowing us to add and delete items from the document. For example, *ngIf, *ngFor, and so on.
  • Attribute directives - to change an element's, component's, or directive's behaviour or appearance.

An element's class attribute defines one or more classnames. The class attribute is typically used to point to a style sheet class. It can, however, be utilised by JavaScript to make changes to HTML components with a defined class (through the HTML DOM).

A class attribute for an element defines one or more classnames. The class attribute is most commonly used to refer to a style sheet's class. It can, however, be used by JavaScript to modify HTML components with a defined class (through the HTML DOM).
