HTMLElement: offsetParent property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The HTMLElement.offsetParent read-only property returns a
reference to the element which is the closest (nearest in the containment hierarchy)
positioned ancestor element.
A positioned ancestor might be:
- a containing block for absolutely-positioned elements
- an element with a different effective zoom value (that is, the product of all zoom scales of its parents) from this element
td,th,tablein case the element itself is static positioned.
If there is no positioned ancestor element, the body is returned.
Note:
offsetParent returns null in the following situations:
- The element or any ancestor has the
displayproperty set tonone. - The element has the
positionproperty set tofixedand its containing block is the viewport. If the containing block is not the viewport,offsetParentreturns the nearest ancestor that forms a containing block, for example, an ancestor withtransform,perspective, orfilterstyles set. - The element is
<body>or<html>.
offsetParent is useful because
offsetTop and
offsetLeft are relative to its padding edge.
Value
An object reference to the element in which the current element is offset.
