無法隱藏菜單中的項目

Question

所以，我有一個簡單的NAV，我試圖添加一個漢堡圖標，只有當屏幕很小時纔會顯示。

目前，我的漢堡只是單詞菜單，但我想默認情況下隱藏它。但是，我的代碼被顯示覆蓋：inline，代碼中較早。即使我添加！重要。

任何人有任何想法，我怎麼可以隱藏菜單元素？

我的代碼如下。

的.html

<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>

你的問題是在這裏

hidden { 
    display: none; !important<---- this important should be inside ";" 
} 

應該

hidden { 
    display: none !important; 
}
