Скачать или смотреть Angular 2025 Tutorial: Build a Draggable & Fullscreen Modal with CDK

In this step-by-step Angular tutorial, we build a fully custom modal popup component from scratch. You’ll learn how to create a reusable modal in Angular 18 or Angular 20, add Cancel / Confirm events, and make it draggable and fullscreen with the Angular CDK.

✨ What you’ll learn in this video:
– Generating a standalone component with Angular CLI
– Using @Input() and @Output() for parent ↔ child communication
– Styling the modal with SCSS (header, body, footer)
– Projecting content into the modal with ng-content
– Adding drag-and-drop behavior with Angular CDK
– Implementing a fullscreen toggle with HostBinding

🔧 Tech used: Angular 18 / Angular 20, Angular CDK, TypeScript, SCSS

📌 Full SCSS code is in the description for copy & paste.
