Question

I have a problem in IE8 with an animation effect. The code works in firefox, safari, chrome… but no in IE8.

The demo is here.

The code I’m using is:

$(function(){
    $("#wrapper").animate({
        backgroundPosition: "-261px center"         
    }, 12000 );
});

I’m using jquery-1.4.3.min.js

Is there a way to make it work in IE8?

— UPDATE —

i’ve created this fiddle and now it works¿?¿?¿ I havent changed nothing.Just copied the fiddle source frame and saved as index3.html and works.

I don’t understand nothing, but its working! Can anyone explain that?

You can see the result here: dev.thepixellary.es/index3.html

— UPDATE 2 —

it works because in fiddle i was using jquery 1.3.2 instead of 1.5.2 but then this code dont work(IE8):

$(".menu li").each(function(idx) {
  $(this).delay(idx * 1000).fadeIn("slow");
});

Answer 1

Animating background-position is technically unsupported by jQuery.

Use the jQuery BackgroundPosition plugin to fix this issue.
