Question

我试图找出如何在切换发生时更改菜单图标按钮...与菜单图标从汉堡包图标变为切换之间的X时的概念相同。我正在使用bootstrap 3框架，由于某些原因我无法在打开和关闭侧栏菜单之间交替显示图标（切换工作正常无法在切换发生时无法更改图标）。我假设这是一个普遍实现的bootstraps CSS和JS框架......非常感谢任何和所有的帮助！

这是Glyphicon的一个示例，但您可以使用任何字体。而不是跨度：在使用fa之前：之前你使用的字体很棒。

CSS：

#wrapper.toggled #menu-toggle span:before {content:'\2212'}

将此处的内容更改为切换类的unicode

<div id="wrapper">
  <a href="#menu-toggle" class="btn btn-primary"  id="menu-toggle"><span class="glyphicon glyphicon-plus"></span></a> 
  </div>

jQuery - 和你一样
