Question

我在小屏幕上遇到问题而我无法理解为什么会出现这种情况。

以下是代码：

<!-- main navigation -->
<nav class="navbar navbar-toggleable-md navbar-light">
  <div class="container">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#mainNav" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="">
      <img class="img-fluid" src="https://twocan.co/public/images/shared/logos/logo-header.png" alt="Learn English with twocan.com" />
    </a>

    <div class="collapse navbar-collapse" id="mainNav">
      <ul class="navbar-nav mr-auto">
        <li class="nav-item">
          <a class="nav-link" href="">
            <i class="fa fa-home" aria-hidden="true"></i>
            Foo
          </a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="">
            <i class="fa fa-certificate"></i>
            Foo
          </a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="">
            <i class="fa fa-lightbulb-o"></i>
            Foo
          </a>
        </li>
      </ul>

      <ul class="navbar-nav ml-auto">

        <li class="nav-item">
          <a class="nav-link" href="">
            <i class="fa fa-sign-in"></i>
            Foo
          </a>
        </li>
        <span class="navbar-text">
          /
        </span>
        <li class="nav-item">
          <a class="nav-link" href="">
            Foo
            <i class="fa fa-check"></i>
          </a>
        </li>
      </ul>
    </div>
  </div>
</nav>
<!-- end main navigation  -->

因为你可以看到汉堡菜单下面的标识......我该如何解决这个问题？

尝试以下代码。我在导航栏中指定了右侧元素，当它崩溃时，所有内容都汇集在一起。我希望这是你正在寻找的东西。

   <nav class="navbar navbar-default">
      <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="">
          <img class="img-fluid" src="https://twocan.co/public/images/shared/logos/logo-header.png" alt="Learn English with twocan.com" /></a>
        </div>
        <div class="collapse navbar-collapse" id="myNavbar">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Foo</a></li>
            <li class="dropdown">
              <a class="dropdown-toggle" data-toggle="dropdown" href="#">Foo Drop<span class="caret"></span></a>
              <ul class="dropdown-menu">
                <li><a href="#">Foo 1 </a></li>
                <li><a href="#">Foo 2</a></li>
                <li><a href="#">Foo 3</a></li>
              </ul>
            </li>
            <li><a href="#">Foo</a></li>
            <li><a href="#">Foo</a></li>
          </ul>

          <!--Right Side-->
          <ul class="nav navbar-nav navbar-right">
            <li><a href="#">Foo R1 </a></li>
            <li><a href="#">Foo R2</a></li>
          </ul>
        </div>
      </div>
    </nav>`enter code here`

不要在导航中嵌套// function to post items to the server function postItems (options, items, done) { items.forEach(function (item, index, items) { var lastItemIndex = items.length - 1 $.post(options.url, { ouch: option.ouch, password: option.password, order_id: option.currentOrderId, widget_id: item[0], number: item[1], pence_price: item[2] }, function (data) { if (index < lastItemIndex) return; return done($.parseJSON(data)); }); }) } // usage postItems({url: "/serverUrl", ouch:'someString', password: 'itsASecret'}, ["item", "collection", "goes", "here"], function(data){ alert(data.message); });。如果需要，您可以在那里使用.container。

你的自定义CSS是嵌套的 - 除非你使用允许嵌套的预处理器，否则CSS不能正常工作。

.container-fluid

.navbar {
    border-bottom: 1px solid #eeeeee;
    }
    .nav-link {
        font-weight: 800;
    }
    .nav-item.active .nav-link {
        color: #7cd97c !important;
    }
