Resize Observer

<mo-resize-observer> | MOResizeObserver
Since 1.0 stable

A component that observes one or more elements for resizing.

The resize observer will report changes to the dimensions of the elements it wraps through the mo-resize event. When emitted, a collection of ResizeObserverEntry objects will be attached to event.detail that contains the target element and information about its dimensions.

  const container = document.querySelector('.resize-observer-overview');
  const resizeObserver = container.querySelector('mo-resize-observer');

  resizeObserver.addEventListener('mo-resize', event => {
