In my recent attempt to build a site with horizontal parallax (sites with multiple moving backgrounds..eg:
http://www.liptonicetea.pl/), i came across an issue where my code would only work in chrome but not in other browsers.
After searching on google i came across some articles stating same issue. I was able to resolve it by
changing the selector i was using for the animation.
Earlier i was using
$(window).animate({"scrollLeft":1100},1500)
I changed it to
$("html,body").animate({"scrollLeft":1100},1500)
and now my code works perfectly fine across all the browsers.
