Render templates from a parent component with `ng-content`

<ng-content> is a special element that accepts markup or a template fragment and controls how components render content. It does not render a real DOM element.

Here is an example of a BaseButton component that accepts any markup from its parent.

base-button/base-button.ts

import {Component} from '@angular/core';

@Component({
  selector: 'button[baseButton]',
  template: `<ng-content />`,
})
export class BaseButton {}

app.ts

import {Component} from '@angular/core';
import {BaseButton} from './base-button';

@Component({
  selector: 'app-root',
  imports: [BaseButton],
  template: `<button baseButton>Next <span class="icon arrow-right"></span></button>`,
})
export class App {}
