HTMLElement: offsetWidth 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 offsetWidth read-only property of the HTMLElement interface 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.
