Element: clientLeft property

The width of the left border of an element in pixels. It includes the width of the vertical scrollbar if the text direction of the element is right-to-left and if there is an overflow causing a left vertical scrollbar to be rendered. clientLeft does not include the left margin or the left padding. clientLeft is read-only.

Note: This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect().

Note: When an element has display: inline, clientLeft returns 0 regardless of the element's border.

Value

A number.

Examples

In the following example, the client area has a white background and a 24px black border-left. The clientLeft value is the distance from where the margin (yellow) area ends and the padding and content areas (white) begin: that is, 24px.
