将jquery中的标题与滑块对齐

以下是http://jsfiddle.net/j88u02o2/59/

html:

<div id="container">
        <div id="example">
            <div id="slides" style="width:1000px;height:430px;"></div>
                <div id="" class="" style="position:relative; width:970px; margin:auto;" align="">
                    <div id="crossSlideCaption" class="caption">
            </div>
        </div>
    </div>

这是我的脚本：

$(function() {
        $('#slides').crossSlide({
            speed: 40,
            fade: 1
        }, [
            { src: 'img/photo-2.jpg', dir: 'up', alt: 'Our Business is to Encrypt and Secure Your Communications', href: '#'  },
            { src: 'img/photo-10.jpg', dir: 'down', alt: 'The Solution for Secured Communications and Privacy.', href: '#'  },
            { src: 'img/photo-3.jpg', dir: 'up', alt: 'All Text and Phone Communications are Encrypted End-to-End.', href: '#'  },
            { src: 'img/photo-4.jpg', dir: 'down', alt: 'Secured Communications for Law Enforcement and Public Officials.', href: '#'  },
            { src: 'img/photo-5.jpg', dir: 'up', alt: 'Secured Communications for the U.S. Military.', href: '#'  },
            { src: 'img/photo-6.jpg', dir: 'down', alt: 'The World Leader in Encrypted Communications.', href: '#'  },
            { src: 'img/photo-7.jpg', dir: 'down', alt: 'The Solution for Corporate Executives, Law Enforcement, Homeland Security, Goverment Agencies and more...', href: '#'  }
        /*  */
        ], function(idx, img, idxOut, imgOut) {
            if (idxOut == undefined) {
                if(idx == 0 || idx == 3 || idx == 6 || idx == 9){
                    document.getElementById('crossSlideCaption').style.marginTop = '0px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-85px';
                }else if(idx == 1 || idx == 4 || idx == 7 || idx == 10 || idx == 12){
                    document.getElementById('crossSlideCaption').style.marginTop = '280px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-100px';
                }else{
                    document.getElementById('crossSlideCaption').style.marginTop = '-52px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-485px';
                };
                $('div.caption').text(img.alt).animate({ opacity: 1.0 })
            } else {
                $('div.caption').animate({ opacity: 0 })
            }});
        $('div.caption').show().css({ opacity: 0 })
    }); 

一切都很好，除了标题。

所以，我尝试了这个代码，

function(idx, img, idxOut, imgOut) {
            if (idxOut == undefined) {
                if(idx == 0 || idx == 3 || idx == 6 || idx == 9){
                    document.getElementById('crossSlideCaption').style.marginTop = '0px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-85px';
                }else if(idx == 1 || idx == 4 || idx == 7 || idx == 10 || idx == 12){
                    document.getElementById('crossSlideCaption').style.marginTop = '280px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-100px';
                }else{
                    document.getElementById('crossSlideCaption').style.marginTop = '-52px';
                    document.getElementById('crossSlideCaption').style.marginBottom = '-485px';
                };

但是，它仍然不起作用，我需要这样的东西http://securedcommunications.com/

也就是说，

当第一张幻灯片->标题将在幻灯片的顶部时

第2张幻灯片-->中间

第三张幻灯片-->底部。[重复]。

有人能帮我找到确切的解决方案吗？

如有任何帮助，我们将不胜感激。

提前谢谢。
