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.
On systems using display scaling, scrollLeft
may give you a decimal value.
Syntax
Getting the value
// Get the number of pixels scrolled var sLeft = element.scrollLeft;
sLeft
is an integer representing the number of pixels that element
has been scrolled from the left edge.
Setting the value
// Set the number of pixels scrolled element.scrollLeft = 10;
scrollLeft
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.
Example
HTML
<div id="container"> <div id="content">Click the button to slide right!</div> </div> <button id="slide" type="button">Slide right</button>
CSS
#container { width: 100px; height: 100px; border: 1px solid #ccc; overflow-x: scroll; } #content { width: 250px; background-color: #ccc; }
JavaScript
const button = document.getElementById('slide'); button.onclick = function () { document.getElementById('container').scrollLeft += 20; };
