aria-hidden
Hides from ARIA everything, except provided node.
Helps to isolate modal dialogs and focused task - the content will be not accessible using
accesible tools.
API
Just call hideOthers
with DOM-node you want to keep, and it will hide everything else.
targetNode could be placed anywhere - its siblings would be hidden, but its parents - not.
import {hideOthers} from 'aria-hidden';
const undo = hideOthers(DOMnode);
undo();
you also may limit the effect by providing top level node as a second paramiter
hideOthers(targetNode, parentNode);
hideOthers(anotherNode, document.getElementById('app'));
Inspiration
Based on smooth-ui modal dialogs.
