Web Components
Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements.
Support for Web Components is present in some WebKit-based browsers like Google Chrome and Opera and is in Mozilla Firefox (requires a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet.[1] Backwards compatibility with older browsers is implemented using JavaScript-based polyfills.
Web Components consist of 4 main elements which can be used separately or all together:
- Custom Elements
- Shadow DOM
- HTML Imports
- HTML Templates
