Custom Elements, Shadow DOM, HTML Templates

Understanding Web Components

Web Components are a set of web platform APIs that allow developers to create reusable, encapsulated custom elements for the web. They work natively in modern browsers without needing external libraries or frameworks. Web Components let you define your own HTML tags with custom behavior, style encapsulation, and reusable functionality.
