ResizeObserverEntries

ResizeObserverEntries are objects returned by the ResizeObserver interface, which is part of the Resize Observer API. This API allows developers to observe changes to the dimensions of an element's content or border box. When a resize event occurs, the ResizeObserver callback function is invoked with a list of ResizeObserverEntry objects, each representing a single resize event.

Each ResizeObserverEntry object contains the following properties:

- contentBoxSize: An array of objects representing the size of the element's content box. Each object contains width and height properties.

- contentRect: A DOMRectReadOnly object representing the size and position of the element's content box.

- borderBoxSize: An array of objects representing the size of the element's border box. Each object contains width and height properties.

- target: The Element or SVGElement whose size has changed.

The ResizeObserverEntries provide detailed information about the resize event, allowing developers to respond appropriately to changes in an element's dimensions. This can be particularly useful for creating responsive layouts, adjusting the size of media elements, or triggering animations based on element size changes.
