我正在进行移动优先设计,并使用CSS和jQuery创建了一个我真正喜欢的下拉汉堡包菜单,但是我想做的是让该汉堡包消失,当页面在桌面上显示并由常规的水平菜单替换时导航栏。我能够使菜单响应,因此至少在桌面上有一个水平导航栏(而不是像在移动设备上那样长的菜单列表),但是我根本不希望它下降—我希望它完全替换该汉堡包图标。我不知道Bootstrap(我是新手),但是任何使用html,css和jQuery的建议都很棒!谢谢!

这是我的代码:

HTML:

     <div id="nav-icon4">

最佳答案

您将需要更新CSS,以便在您希望其可见的断点处显示“汉堡包”按钮。

当前,您已将其设置为显示在(min-width: 300px)处,但您的导航看起来像是以601px的大屏幕视图。因此,您只想让汉堡包也不显示601px。

在单独的注释上,我看到您是这样构造汉堡包的:

 <div id="nav-icon4">
  <span></span>
  <span></span>
  <span></span>
 </div>


我强烈建议您将此代码修改为以下内容:

<button type="button" id="nav-icon4" aria-label="Menu">
  <span></span>
  <span></span>
  <span></span>
</button>


这样,键盘用户将可以访问该按钮。
