HTMLElement.offsetHeight
The HTMLElement.offsetHeight
read-only property is the height of the element including vertical padding and borders, in pixels, as an integer.
Typically, an element's offsetHeight
is a measurement which includes the element borders, the element vertical padding, the element horizontal scrollbar (if present, if rendered) and the element CSS height.
For the document body object, the measurement includes total linear content height instead of the element CSS height. Floated elements extending below other linear content are ignored.
This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect()
.
Syntax
var intElemOffsetHeight = document.getElementById(id_attribute_value).offsetHeight;
intElemOffsetHeight is a variable storing an integer corresponding to the offsetHeight pixel value of the element. The offsetHeight property is readonly.
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.
