The HTMLElement.offsetHeight
read-only property returns the height of an element, including vertical padding and borders, as an integer.
Typically, offsetHeight
is a measurement in pixels of the element's CSS height, including any borders, padding, and horizontal scrollbars (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.
If the element is hidden (for example, by setting style.display
on the element or one of its ancestors to "none"
), then 0
is returned.
This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect()
.
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.
