clientTop property
The width of the top border of an element in pixels. It is a read-only, integer property of element.
As it happens, all that lies between the two locations (offsetTop and
client area top) 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, (client area includes padding.)
Therefore, the
clientTop value will always equal the integer portion of the
.getComputedStyle() value for "border-top-width". (Actually might be
Math.round(parseFloat()).) For example, if the computed "border-top-width"
is zero,
then clientTop is also zero.
Note: This property will round the value to an integer. If you need a fractional value, use
element.getBoundingClientRect.
Implementation
external int get clientTop;
