我在使用zurb基础在Drupal 8中创建顶级菜单时遇到问题 . 我目前正在使用sass和gulp . 当我打开foundation.css文件时，我找不到css class =“title-area”，class =“toggle-topbar menu-icon”和class =“top-bar-section” . 我下载了zurb foundation framewaork的完整包 . 这是代码 .
<nav class="top-bar" data-topbar role="navigation">
<ul class="title-area">
<li class="name">
<h1><a href="#">My Site</a></h1>
</li>
<!-- Remove the class "menu-icon" to get rid of menu icon. Take out "Menu" to just have icon alone -->
<li class="toggle-topbar menu-icon"><a href="#"><span>Menu</span></a></li>
</ul>
<section class="top-bar-section">
<!-- Right Nav Section -->
<ul class="right">
<li class="active"><a href="#">Right Button Active</a></li>
<li class="has-dropdown">
<a href="#">Right Button Dropdown</a>
<ul class="dropdown">
<li><a href="#">First link in dropdown</a></li>
<li class="active"><a href="#">Active link in dropdown</a></li>
</ul>
</li>
</ul>
<!-- Left Nav Section -->
<ul class="left">
<li><a href="#">Left Nav Button</a></li>
</ul>
</section>
</nav>
这就是它的显示方式
