Web Components Custom

Web Components is a suite of standards (Custom Elements, Shadow DOM, HTML Templates, Slots) for creating encapsulated, reusable UI elements. Unlike frameworks, Web Components are native browser APIs—any modern browser understands them without build tools or transpilation. Custom elements extend HTML with new tags (e.g., ), Shadow DOM isolates styles and DOM, and slots allow content projection. Web Components power design systems, component libraries, and framework-agnostic UI tooling. They enable code reuse across React, Vue, Angular, and vanilla JavaScript.
