jQuery fadeTo effect is having problem in IE

I am trying to make the opac开发者_StackOverflow社区ity of body to 0 for some time and then make it to 1. But the problem is in IE after getting the opacity to 1, page is looking some how different.

The reason that it's rendered differently is because there is still a filter applied to the body. Although the filter has no visible effect due to it's settings, the rendering still has to support the filter as it's there.

You have to examine how the opacity is set, and make sure that the filter is removed once it's not needed any more.

IE has trouble with opacity and anti-aliasing. It helps to set a background-color on the element you're fading.
Also, fadeTo act a little different: you might have better luck with .fadeIn() and .fadeOut().
