HTML 5 Web Component Fundamentals

HTML5 Web Components are a set of modern web technologies that allow developers to create reusable, custom HTML elements. They help in building clean, modular, and maintainable web applications.

This topic covers the core concepts of Web Components, including Custom Elements, Shadow DOM, HTML Templates, and Encapsulation. You will learn how to create your own HTML tags, style them independently, and reuse them across different projects.

By understanding Web Component fundamentals, learners can build scalable user interfaces, reduce code duplication, and write more organized front-end code using standard browser features without external frameworks.

What Are Web Components?

Web Components are a collection of technologies that let you define custom HTML elements with their own structure, style, and behavior. These components can be reused multiple times across a website or application, just like standard HTML elements such as <div> or <button>.

For example, instead of rewriting the same navigation bar or card layout again and again, you can create a single custom component and use it everywhere.
