How can I create custom directives in my application?

Creating custom directives involves defining a new directive in your framework, like Angular or Vue. What framework are you using?

I'm using Angular. Can you give me a basic example?

Sure! In Angular, you can create a custom directive by using the @Directive decorator. Here's a simple example:

import { Directive, ElementRef, Renderer2 } from '@angular/core';

@Directive({
  selector: '[appHighlight]'
})
export class HighlightDirective {
  constructor(el: ElementRef, renderer: Renderer2) {
    renderer.setStyle(el.nativeElement, 'backgroundColor', 'yellow');
  }
}

This directive highlights the background of an element.

That looks great! How do I use this directive in my template?

You can use the directive in your template by adding the selector as an attribute to an HTML element. For example:

<p appHighlight>This text will be highlighted.</p>

This will apply the highlight effect to the paragraph.
