In fact, the React docs use it as the primary example for how Portals work: See the Pen Example: Portals by Dan Abramov on CodePen.. It's the same concept, where a Portal component is created and a state is used to append the its child elements to the Modal component To fetch the elements' property, React gives something called as 'ref'. Using ref we can create a direct reference to any HTML elements and get controlled over HTML elements properties. Here we use the 'ref' system to fetch image height and width. Example 1: This example illustrates how to fetch the current height and width of the image
