[jQuery] dom ready takes very long in IE 8

[jQuery] dom ready takes very long in IE 8


I am hiding a login panel like:
$(document).ready(function() {
    $("#login").css({marginTop: "-105px"});
});
But in IE 8 it takes very long to hide? I don't like to set it in CSS
because if javascript is turned off people can still login as it is
visible... is there anyway to make it faster ?
