DOMRectReadOnly.width Read only

The width of the DOMRect.

DOMRectReadOnly.height Read only

The height of the DOMRect.

DOMRectReadOnly.top Read only

Returns the top coordinate value of the DOMRect (usually the same as y).

DOMRectReadOnly.right Read only

Returns the right coordinate value of the DOMRect (usually the same as x + width).

DOMRectReadOnly.bottom Read only

Returns the bottom coordinate value of the DOMRect (usually the same as y + height).

DOMRectReadOnly.left Read only
