DOM

MDC DOM provides commonly-used utilities for inspecting, traversing, and manipulating the DOM.

Most of the time, you shouldn't need to depend on mdc-dom directly. It is useful however if you'd like to write custom components that follow MDC Web's pattern and elegantly integrate with the MDC Web ecosystem.

Installation

npm install @material/dom

Basic Usage

import * as ponyfill from '@material/dom/ponyfill';

See Importing the JS component for more information on how to import JavaScript.
