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