引導漢堡圖標動畫導航欄頭

如何使菜單按鈕漢堡動畫到X在引導navbar-fixed-top？

<nav class="navbar navbar-default navbar-fixed-top"> 
      <div class="container"> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
       <span class="sr-only">Toggle navigation</span> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
       </button> 
       <a class="navbar-brand" href="index.html">Logo</a> 
      </div> 
      <div id="navbar" class="navbar-collapse collapse"> 
       <ul class="nav navbar-nav"> 
       <li><a href="#">Menu1</a></li> 
       <li><a href="#">Menu2</a></li> 
       <li><a href="#">Menu3</a></li> 
       </ul> 

      </div><!--/.nav-collapse --> 

      </div> 
</nav>

我試圖在所有可能的例子堵塞，但我錯過了點。有任何想法嗎？

非常感謝。

首先，你需要關閉按鈕創建額外的標記

<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
      <span class="sr-only">Toggle navigation</span> 
      <div class="burger> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      </div> 
      <div class="close"> 
       x 
      </div> 
      </button>

所以，在那之後，你需要更新你的CSS：

.navbar-toggle .burger{ 
    display: none; 
} 
.navbar-toggle .close{ 
    display: block; 
} 

.navbar-toggle.collapsed .burger{ 
    display: block; 
} 
.navbar-toggle.collapsed .close{ 
    display: none; 
}

附：你也可以很容易地默認之間添加動畫和.collapsed類

你問如何設置過渡動畫效果，我覺得jQuery的是爲這個偉大的。

$(".navbar-toggle").click(function() { 
 
    $(".open").toggle(500).siblings().toggle(500); 
 
});

.close { 
 
display:none; 
 
}

據工作@nfm！多謝！是否有可能使用類似於這些[示例]（https://codepen.io/designcouch/pen/Atyop）的jQuery獲取動畫？ –
