[javascript] How to move an entire div element up x pixels?

I want to reposition an entire div and its contents up about 10-15 pixels.

How can I do this?

Note: this is slider element, so when I click a button the slider slides down. Once it is finished I want to reposition it up about 15 pixels.

In css add this to the element:

margin-top: -15px; /*for exact positioning */
margin-top: -5%; /* for relative positioning */

you can use either one to position accordingly.

$('div').css({
    position: 'relative',
    top: '-15px'
});

you can also do this

margin-top:-30px; 
min-height:40px;

this "help" to stop the div yanking everything up a bit.
