HTMLElement: offsetWidth property
The HTMLElement.offsetWidth
read-only property returns
the layout width of an element as an integer.
Typically, offsetWidth
is a measurement in pixels of the element's CSS
width, including any borders, padding, and vertical scrollbars (if rendered). It does
not include the width of pseudo-elements such as ::before
or
::after
.
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.
Value
An integer corresponding to the offsetWidth
pixel value of the element. The offsetWidth
property is a read-only.
Note: This property will round the value to an integer. If you need a fractional value, use
element.getBoundingClientRect()
.
