I do a fade in div that is not displayed when I load the page:
$(\'#overlay\').fadeIn(\'fast\');
$(\'#box\').fadeIn(\'slow\');
I would
Maybe this is too late to reply but I found a way which helped me.
$("#overlay").fadeTo(10000,1).fadeOut(5000);
Refer this link http://juristr.com/blog/2009/12/howto-fade-out-div-after-some-seconds/
It allows you to set a time like when you want the div to disappear and with what speed.
You could use setTimeout()
var xSeconds = 1000; // 1 second
setTimeout(function() {
$('#overlay').fadeOut('fast');
$('#box').hide();
}, xSeconds);
The .delay method is purpose built for what you are describing:
$('#overlay').fadeIn('fast').delay(1000).fadeOut('fast');
$('#box').fadeIn('slow').delay(1000).hide(0);
