Question

我最近想在我的网站上添加一些媒体查询行，这一切都很完美，直到我添加了一个移动导航（下拉菜单）。在那之后，我的选框以某种方式落后于标题（导航），之后，我无法弄清楚出了什么问题。

我不想用填充来移动它，而是想弄清楚为什么会这样，因为在我添加移动导航之前，所有东西都有其特定的位置而不是一件事重叠另一件事。

这是我的HTML：

   <body> 
    <div id="container">
        <header>
        <div id="nav">
            <nav class="nav-collapse">
            <ul>
                <li><img alt="icon" src="res/img/logo2.png"></li>
                <li><a rel="alternate" href="#" class="current" class="nav-collapse">Home</a></li>
                <li><a href="sub/menu1.html">Members</a></li>
                <li><a href="sub/menu2.html">Exams</a></li>
                <li><a href="sub/menu3.html">Timetable</a> </li>
                <li><a href="sub/menu4.html">About</a></li>
                <li><a class="fck" href="password.html">Private Site</a</li>
                <li id="title">Class Site</li>
            </ul>
            </nav>
        </div>
        </header>

        <div id="content">
            <div id="title">
                <div class="marquee">
                     <h3>Welcoke...</h3>
                </div>
            </div>
            <div id="article" text-align="center">Website was made by ŽP, JM and TM!

尝试使用navbar-fixed-top将导航栏固定到顶部，然后为正文提供50像素的padding-top。
