jquery - How to position horizontal scroll bar at center of DIV

Question

I was trying to position horizontal scroll bar at the center of that div. I tired with window.scrollTo() but this works for page scroll and not for div scroll.

$(document).ready(function(){
    var outerContentWidth = $('.abc').width();
    var scrollPosition = outerContentWidth/2;
    $('.abc').scrollLeft(scrollPosition);

});

The following will give you your desired effect and scroll to the center of the div through a simple change in your jQuery:

$(document).ready(function(){
    var outerContent = $('.abc');
    var innerContent = $('.abc > div');

    outerContent.scrollLeft((innerContent.width() - outerContent.width()) / 2);        
});

This code will set the scroll bar to the center of the inner content. But lets examine why. We know the minimum value for scrollLeft is zero, and the maximum is inner.width() - outer.width(). So, half way is easily half the maximum.

There is plenty more information on the subject here.
