Everything about Shadow DOM

Web platform API for DOM encapsulation

Shadow DOM is a browser feature that allows websites to define self-contained HTML elements on the website. These self-contained elements, called shadow trees, allow website developers to bundle together related HTML markup and CSS styling in a manner such that the styling and code does not affect other surrounding elements. This solves a recurring problem that web developers face of unintended interference between components, where CSS rules written for one part of a page can accidentally affect unrelated parts of the website.
