Element: clientTop 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 clientTop
read-only property of the Element
interface returns the width of the top border of an element in pixels.
All that lies between the offsetTop
and clientTop
is the element's border. This is because the offsetTop
indicates the location of the top of the border (not the margin) while the client area starts immediately below the border, including padding. Therefore, the clientTop
value is always equal to the border-top-width
, rounded to integer. For example, if the computed border-top-width
is zero, then clientTop
is also zero.
Value
An integer.
Examples
In the following example, the client area has a white background and a 24px black border-top
. The clientTop
value is the distance from where the margin (yellow) area ends and the padding and content areas (white) begin: that is, 24px.
