A polyfill for document.scrollingElement
as defined in the CSSDOM specification
npm install scrolling-element --save
In an HTML document:
<script src="scrolling-element.js"></script>
For Babel and ES2015+, just import the file
import 'scrolling-element'
Thanks to Mathias Bynens for his document.scrollingElement, and for allowing me to simplify the polyfill
