Custom Elements (deprecated V0 spec)

Last updated on : 2023-03-20

Note:

Custom Elements (deprecated V0 spec) shows a browser compatibility score of 0. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

The custom-elements package provides a native, easy way to define and use custom elements in JavaScript. It has been extracted from the main Web Components standards effort, based on our experience with real-world use cases.
