HTMLElement.offsetHeight

The HTMLElement.offsetHeight read-only property is the height of the element including vertical padding and borders, as an integer.

Typically, an element's offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar (if present, if rendered). It does not include the height of pseudo-elements such as :before or :after.

For the document body object, the measurement includes total linear content height instead of the element's CSS height. Floated elements extending below other linear content are ignored.

Syntax

var intElemOffsetHeight = element.offsetHeight;

intElemOffsetHeight is a variable storing an integer corresponding to the offsetHeight pixel value of the element. The offsetHeight property is read-only.

Example

The example image above shows a scrollbar and an offsetHeight which fits on the window. However, non-scrollable elements may have large offsetHeight values, much larger than the visible content. These elements are typically contained within scrollable elements; consequently these non-scrollable elements may be completely or partly invisible, depending on the scrollTop setting of the scrollable container.

Specification

Notes

offsetHeight is a property of the DHTML object model which was first introduced by MSIE. It is sometimes referred to as an element's physical/graphical dimensions, or an element's border-box height.

Browser compatibility

In compliance with the specification, this property will return null on Webkit if the element is hidden (the style.display of this element or any ancestor is "none") or if the style.position of the element itself is set to "fixed".

This property will return null on Internet Explorer (9) if the style.position of the element itself is set to "fixed". (Having display:none does not affect this browser.)
