【问题描述】：

我正在尝试学习一些前端开发，我发现了一件有趣的事情 [这里][1]。每当我向左或向右移动光标时，我想保持滑动效果，但导航栏是静态/固定的。

【问题讨论】：

把JS中的事件监听去掉就不动了。
@shubham - 我想使用这些动画。
你想要动画吗？事件侦听器使导航栏左右移动。你想让这些移动吗？请让您的问题更清楚。

CSS 来制作固定的导航栏

nav{
position:fixed !important;
width:100% !important
}

nav{
position:fixed !important;
width:100% !important
}

<div class="container" style="margin-top:50px">
  <h3>Fixed Navbar</h3>
  <div class="row">
    <div class="col-md-4">
      <p>A fixed navigation bar stays visible in a fixed position (top or bottom) independent of the page scroll.</p>
