To create a custom Angular directive, you define a class and decorate it with the `@Directive` decorator. Within this class, you can specify the directive's behavior by implementing methods such as `ngOnInit`, `ngOnChanges`, or using lifecycle hooks. You also define the directive's selector, which determines how it is applied in the template. Custom directives can be used to manipulate the DOM, add custom behavior to elements, or create reusable components. For example, you might create a directive to change the background color of an element based on certain conditions.
