我正在编辑网站模板的下载版本。我只是想问是否有人可以帮助我找到一种方法来停止向下滚动该标题的所有网站页面。我的标头代码如下：
<header class="main_menu_area">
<nav class="navbar navbar-expand-xl navbar-light bg-light">
<a class="navbar-brand" href="#"><img src="img/logosofto.png" alt="" width="250" height="240"></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span></span>
<span></span>
<span></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav">
<li class="nav-item active"><a class="nav-link" href="index.html"><font size="+1">Home</font></a></li>
<li class="nav-item"><a class="nav-link" href="about-us.html"><font size="+1">About Us</font></a></li>
<li class="nav-item"><a class="nav-link" href="service.html"><font size="+1">Services</font></a></li>
<li class="nav-item"><a class="nav-link" href="portfolio.html"><font size="+1">Portfolio</font></a></li>
<li class="nav-item dropdown submenu">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<font size="+1">Blog</font>
</a>
<ul class="dropdown-menu" aria-labelledby="navbarDropdown">
<li class="nav-item"><a class="nav-link" href="blog.html">Blog</a></li>
<li class="nav-item"><a class="nav-link" href="single-blog.html">Blog Details</a></li>
<li class="nav-item"><a class="nav-link" href="elements.html">Elements</a></li>
</ul>
</li>
<li class="nav-item"><a class="nav-link" href="contact.html"><font size="+1">Contact</font></a></li>
</ul>
</div>
</nav>
</header>
我只能假设你使用的是引导框架。您的导航标记是否包含导航栏固定或类似内容。
<nav class=“navbar-fixed”>
