Element: clientWidth property
{{APIRef("DOM")}}
The clientWidth read-only property of the {{domxref("Element")}}Element interface is zero for inline elements and elements with no CSS; otherwise, it's the inner width of an element in pixels. It includes padding but excludes borders, margins, and vertical scrollbars (if present).
When clientWidth is used on the root element (the <html> element), (or on <body> if the document is in quirks mode), the viewport's width (excluding any scrollbar) is returned.
Value
An integer.
