Web Development Intermediate

What is Web Components?

A set of browser-native APIs for creating reusable, encapsulated custom HTML elements with their own styling and behavior.

Web Components use three main technologies: Custom Elements (define new HTML tags), Shadow DOM (encapsulated styling and markup), and HTML Templates (reusable markup structures). They work natively in modern browsers without frameworks.

Web Components are framework-agnostic — use them with React, Vue, Angular, or vanilla JavaScript. Libraries like Lit simplify Web Component development. They are ideal for design systems and shareable UI components.
