Is there a way I am able to add

var divTop = (viewportheight - 500)/2;

into:



<script type="text/javascript">

$(document).ready( function() {

                var divTop = (viewportheight - 500)/2;

                $("#inner").css({margin-top : divTop})

		$('#rons_list').accordion({
			active: false,
			header: '.head',
			navigation: true,
			event: 'mouseover',
			fillSpace: true,
			animated: 'easeslide'
		});
	 });
</script>
