如何使用标题在标题幻灯片中制作内容

Question

理想情况下，我希望标题中的内容向上滚动以仅显示导航列表并在用户滚动时隐藏徽标（因此当用户滚动时，标题不会在屏幕上占用太多空间查看网站）。知道我做错了什么吗？截至目前，标题背景向上滑动，但标题中的内容保持原位。我假设我缺少一个简单的解决方案，谢谢。

HTML

<div id="header">
   <div id="address">
        <ul>
            <li>Address</li>
            <li>info@email.com</li>
            <li>(999) 999 9999</li>
        </ul>
    </div>

    <p id="logo">
        <img src="img/logo.png" />
    </p>

    <nav>
        <ul>
            <li><a href="#slider">Home</a></li>
            <li><a href="#wwd">What</a></li>
            <li><a href="#hwdi">How</a></li>
            <li><a href="#aboutanchor">Who</a></li>
            <li><a href="#workanchor">Work</a></li>
            <li><a href="#contact">Contact</a></li>
        </ul>
    </nav>
    <div style="clear:both;"></div>
</div>

CSS

        font-size: 1.4em;
        color: #333 !important;
        position: relative;
        top: 2px;

    nav ul li a {

        display: block;

        text-transform: uppercase;
        font-weight: 800;
        transition: color .2s ease-in-out;
    }

    nav ul li a:hover {
        color: #95c73a;
    }

jQuery

$(function(){
        $('#header').data('size','big');
    });

    $(window).scroll(function(){
        var $nav = $('#header');
        if ($('body').scrollTop() > 0) {
            if ($nav.data('size') == 'big') {
                $nav.data('size','small').stop().animate({
                    height:'80px'
                }, 600);
            }
        } else {
            if ($nav.data('size') == 'small') {
                $nav.data('size','big').stop().animate({
                    height:'165px'
                }, 600);
            }
