1. 첫번째 방법

 - 가운데 정렬일경우 항상 같은위치에 고정 

<script language="JavaScript">

    function adjustDivs()

    {

        var df   = document.getElementById('divQuickMenu');

        var left = 0;

        if (window.innerWidth)

        {

            if(window.innerWidth < 876) left = 452

            else                        left = window.innerWidth / 2;

        }

        else

        {

            var obj = document.documentElement;

            if(obj.offsetWidth < 876) left = 452

            else                      left = obj.offsetWidth / 2;

        }

        df.style.left = left + 440;

        df.style.top  = 80 + obj.scrollTop;

        df.style.display = 'block';

    }

    function window::onload()       {      adjustDivs();    }

    function window::onresize()     {      adjustDivs();    }

    function window::onscroll()     {      adjustDivs();    }

</script>

<div id="divQuickMenu" style="position:absolute; display:none;">

    <table border="0" cellspacing="0" cellpadding="0">

        <tbody><tr>

            <td>퀵메뉴</td>

        </tr>

    </tbody></table>

</div>
