Element.scrollLeft
The Element.scrollLeft
property gets or sets the number
of pixels that an element's content is scrolled from its left edge.
If the element's direction
is rtl
(right-to-left), then
scrollLeft
is 0
when the scrollbar is at its rightmost
position (at the start of the scrolled content), and then increasingly negative as you
scroll towards the end of the content.
It can be specified as any integer value. However:
-
If the element can't be scrolled (e.g., it has no overflow),
scrollLeft
is set to0
. -
If specified as a value less than
0
(greater than0
for right-to-left elements),scrollLeft
is set to0
. -
If specified as a value greater than the maximum that the content can be scrolled,
scrollLeft
is set to the maximum.
Warning: On systems using display scaling, scrollLeft
may give you a decimal
value.
Value
A number.
