Properties
ReadonlyborderBoxSize
The borderBoxSize read-only property of the ResizeObserverEntry interface returns an array containing the new border box size of the observed element when the callback is run.
ReadonlycontentBoxSize
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.
ReadonlycontentRect
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.
ReadonlydevicePixelContentBoxSize
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.
Readonlytarget
The target read-only property of the ResizeObserverEntry interface returns a reference to the Element or SVGElement that is being observed.
The
ResizeObserverEntryinterface represents the object passed to the ResizeObserver() constructor's callback function, which allows you to access the new dimensions of the Element or SVGElement being observed.MDN Reference
