Properties

borderBoxSize → JSArray<ResizeObserverSize>

no setter
contentBoxSize → JSArray<ResizeObserverSize>
The contentBoxSize read-only property of the ResizeObserverEntry interface returns an array containing the new content box size of the observed element when the callback is run.
no setter
contentRect → DOMRectReadOnly
The contentRect read-only property of the ResizeObserverEntry interface returns a DOMRectReadOnly object containing the new size of the observed element when the callback is run. Note that this is better supported than ResizeObserverEntry.borderBoxSize or ResizeObserverEntry.contentBoxSize, but it is left over from an earlier implementation of the Resize Observer API, is still included in the spec for web compat reasons, and may be deprecated in future versions.

The devicePixelContentBoxSize read-only property of the ResizeObserverEntry interface returns an array containing the size in device pixels of the observed element when the callback is run.
