javascript - 具有可折叠和不可折叠元素的导航栏

Question

我需要在 Bootstrap 中创建一个导航栏，它在桌面上显示如下图。 (图 1)

在移动设备上，我希望将其折叠起来，如图 2 草图所示。

为此，我使用了如下代码和 Bootstrap 。

<div>

<nav class="navbar navbar-default navbar-fixed-top">

  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span> 
      </button>
      <a class="navbar-brand" href="#">WebSiteName</a>
    </div>
    <div class="collapse navbar-collapse" id="myNavbar">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">Page 1</a></li>
        <li><a href="#">Page 2</a></li> 
        <li><a href="#">Page 3</a></li> 
      </ul>

    </div>
    <div>
        <ul class="nav navbar-nav navbar-right">
        <li><a href="#"><span class="glyphicon glyphicon-user"></span> My Profile</a></li>
        <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Post</a></li>
      </ul>
    </div>
  </div>

</nav>

</div>

当屏幕尺寸缩小时，移动 View 中的图像是我想要的，因此只显示字形。

请让我知道您的想法，因为我是新手。 JsFiddle is here.

Answer 1

这是实现此目的的一种方法的示例:nav 被重组为列，以便说明固定的正确图标。

.wrapper {
  padding-left: 15px;
  padding-right: 15px;
  padding-bottom: 75px;
  margin: 0 auto;
}
.wrapper .navbar-default {
  border: transparent;
  margin: 0px;
  padding: 0px;
  width: 100%;
  border-bottom: 6px solid #266080;
  height: 56px;
  position: fixed;
  border-radius: 0px;
}
.navbar-toggle {
  right: 35%;
}
.navbar-collapse {
  background: #f5f5f5;
}
.no-gutter >[class*='col-'] {
  padding-right: 0;
  padding-left: 0;
}
.login {
  display: inline;
  position: fixed;
  width: 100%;
  height: 56px;
  margin: 0px;
  padding: 0px 0px 0px 25px;
  border: transparent;
  border-radius: 0px;
}
.login .glyphicon {
  padding: 10px 5px;
  margin: 0 auto;
}
.login p {
  display: inline;
  padding: 0;
}
.main-content {
  padding: 0 50px;
  margin: 0 auto;
}
@media (max-width: 768px) {
  .login .glyphicon {
    padding: 10px 0px;
  }
  .login {
    padding: 0;
  }
}

  <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up
    one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum
    et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section
    1.10.32.
