响应式菜单在我的网站上无法正常工作

标签： html css

这是我的代码：

<meta name="viewport" content="width=device-width, initial-scale=1">

<link href="css/bootstrap.min.css" rel="stylesheet" media="screen">
<link href="css/style_inventive.css" rel="stylesheet" media="screen">

其中style_inventive.css是我用于菜单的样式表

这是CSS文件内容

@media (min-width: 768px){
.navbar-right .dropdown-menu {

   right: auto; 

 }}

 .nav>li>a:hover
  {
    background-color: #336699;
    color:#fff;
   }
  .dropdown-menu
  {
    margin: 0px;
    padding-top :0px;
    padding-bottom: 0px;
    color: #fff;
  }
 .dropdown-menu>li>a:hover
  {
      background-color: #336699;
      color:#fff;
  }

  .dropdown-menu li
   {
     height: 40;
     color: #fff;
     float: none;
     display: block;
     margin: 0;
     text-align: left;
     border: 0;
     border-bottom: 1px solid #d5d5d5;
  }
  .dropdown-menu a
  {     
     margin-top: 10;    
  }

这是菜单的HTML代码

<div class="col-sm-7 menu">
        <div class="collapse navbar-collapse">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-responsive-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <ul class="nav navbar-nav navbar-right">

                    <a href="#" id="acompany" class="dropdown-toggle" data-toggle="dropdown">COMPANY </a>
                    <ul class="dropdown-menu" role="menu">

                    </ul>
                </li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">SERVICE </a>
                    <ul class="dropdown-menu" role="menu">

                    </ul>
                </li>                   
                <li><a href="product.html">PORTFOLIO</a></li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">TECHNOLOGY </a>
                    <ul class="dropdown-menu" role="menu">
                        <li><a href="php.html">PHP</a></li>
                        <li><a href="java.html">JAVA</a></li>
                        <li><a href="android.html">Android</a></li>
                        <li><a href="dotnet.html">.Net</a></li>
                        <li><a href="ios.html">iOS</a></li>
                    </ul>
                </li>
                <li><a href="sitemap.html">SITEMAP</a></li>
            </ul>
        </div>                                       
    </div>

除了菜单，我调整浏览器大小时会显示所有内容。 调整大小时不显示菜单。

我添加了一些可能不在您的代码中的代码 工作模式

@media (min-width: 768px) {
  .navbar-right .dropdown-menu {
    right: auto;
  }
}

.nav>li>a:hover {
  background-color: #336699;
  color: #fff;
}

.dropdown-menu {
  margin: 0px;
  padding-top: 0px;
  padding-bottom: 0px;
  color: #fff;
}

.dropdown-menu>li>a:hover {
  background-color: #336699;
  color: #fff;
}

.dropdown-menu li {
  height: 40;
  color: #fff;
  float: none;
  display: block;
  margin: 0;
  text-align: left;
  border: 0;
  border-bottom: 1px solid #d5d5d5;
}

.dropdown-menu a {
  margin-top: 10;
}

答案 1 :(得分：1)

我刚刚根据bootstrap example工作更新了html结构。

  1. 如果您看到bootstrap示例，则在{my}之外使用navbar-header collapse navbar-collapse但在你的情况下你错过了它。
  2. 第二个你的目标是navbar-responsive-collapse data-target=".navbar-responsive-collapse"但您还没有定义 它与navbar-collapse一起，所以我只是添加示例目标ID data-target="#bs-example-navbar-collapse-1"并在<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">中定义。
  3. 我只是在navbar navbar-default中选择了另一个元素col-sm-7 menu这是您在没有navbar的情况下错过的重要事情 上课它显然不起作用。

    4. 请参阅fiddle 

    <div class="col-sm-7 menu">
  <nav class="navbar navbar-default">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Brand</a>
    </div>
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav navbar-right">
        <li><a href="home_inventive.html">HOME</a></li>
        <li class="dropdown" id="licompany">
          <a href="#" id="acompany" class="dropdown-toggle" data-toggle="dropdown">COMPANY </a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="about_us.html">About Us</a></li>
            <li><a href="team.html">Meet The Team</a></li>
            <li><a href="join_us.html">Join Us</a></li>
          </ul>
        </li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">SERVICE </a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="mobile_app_development.html">Mobile App Development</a></li>
            <li><a href="software_development.html">Software Development</a></li>
            <li><a href="web_development.html"> Web development</a></li>

          </ul>
        </li>
        <li><a href="product.html">PORTFOLIO</a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">TECHNOLOGY </a>

使用以下代码检查我在代码中所做的更改后看看

第1个你错过了<nav class="navbar navbar-default">导航栏和第2个你错过了<div class="navbar-header">移动屏幕导航栏如果你错过了父类，它会应用课程，而且菜单也没有响应。

@media (min-width: 768px){

   right: auto;
