React Portal Basics

Why Portals?

A great use case for portals is for use with things like React modals. Anything that uses a stack context can obscure the css position for something like a modal.

The tl;dr is to make a React component a descendent of a HTML element other than id="root";

Creating a Portal

import React from "react"; import ReactDOM from "react-dom"; const Modal = (props) => { return ReactDOM.createPortal( <div className="modal"> <div className="modal-body" /> </div>, document.querySelector("#modal") ); };
