jquery - Logo 不会滑落(HTML、CSS、jQuery)

Question

当用户单击“登录”时，我使用 jQuery 将登录框向下滑动。单击时，我希望整个页面向下滑动，包括 Logo 。至此，页面确实下滑了，除了logo。您可以在此处查看页面:

http://mini.lukedude5.com

单击“登录”或“注册”时，页面正文会向下滑动(将底部边距设置为 500 像素以放大它)。但是，正如您所见，“mi.ni” Logo 并没有滑落。

<div id = 'header'>
    <a href = '/' title = 'mi.ni' id = 'logo'>mi.ni</a>
</div>

上面是 Logo 的 HTML，下面是 CSS。

#wrapper
{
    width: 1000px;
    margin-left: auto;
    margin-right: auto;
}

#wrapper #header
{
    height: 100px;
    width: 260px;
    background: url('/styles/images/logo2.png') no-repeat;
    margin: 20px auto 0px auto;
}

#wrapper #header #logo
{
    height: 100px;
    width: 260px;
    display: block;
    text-indent: -9999px;
}

header 被包装在包装器中。登录框从中滑下的栏不在包装内。

登录/向上框的 CSS 是:

#topBar #signIn, #signUp
{
    width: 250px;
    float: right;
    color: #FFF;
    margin-top: 5px;
    font-weight: bold;
    display: none;
    margin-bottom: 500px;
}

感谢任何有关此问题的帮助!

编辑:横跨页面顶部的栏的 HTML。

<div id = 'topBarWrapper'>
        <div id = 'topBar'>
            <div id = 'mainTop'>

在包装器 div 上设置 clear:both。那里正在崩溃。

#wrapper {
width: 1000px;
margin-left: auto;
margin-right: auto;
clear: both;
}
