Yesterday, we looked at the
Element.getBoundingClientRect() method, and how you can use it to get details about an element’s position in the viewport.
Today, let’s look at how to get the height and width of the viewport itself. This one is short-and-sweet.
You can use the
window.innerHeight property to get the viewport height, and the
window.innerWidth to get its width.
let viewportHeight = window.innerHeight; let viewportWidth = window.innerWidth;
