Question

所以，我想出了一个简单的资产净值，而我正在尝试添加一个仅在屏幕较小时显示的汉堡图标。

目前，我的汉堡只是单词Menu，但我希望默认情况下隐藏它。但是，我的代码被显示重写：inline，即代码中的早期代码。即使我添加！重要。

任何人都对如何隐藏菜单元素有任何想法？

我的代码如下。

html的

<div class="nav">
   <ul>
    <li class="hidden">Menu</li>
    <li class="home"><a class="active" href="#">Home</a></li>
    <li class="gallery"><a href="#">Gallery</a></li>
    <li class="tutorials"><a href="#">Tutorials</a></li>
    <li class="about"><a href="#">About</a></li>
  </ul>
</div>
