导航栏标题中的Bootstrap Hamburger图标动画

Question

今天是个好日子，

如何使菜单“汉堡包”按钮在bootstrap navbar-fixed-top中动画为X ？

 <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>

我试图插入所有可能的示例，但我没有指出要点。 有任何想法吗？

非常感谢。

您问过如何为过渡设置动画，我认为jQuery对此非常有用。

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

 .close { display:none; }

首先，您需要为关闭按钮创建其他标记

<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>

因此，之后，您需要更新CSS：

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

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

PS还可以轻松在默认类和.collapsed类之间添加动画
