引导栏3.3.4中的CSS覆盖在导航栏中消除背景色时不起作用

[英]css override in bootstrap 3.3.4 not working when eliminating background color in navbar

 原文  2015-05-17 04:43:12  1   1    html/ css/ twitter-bootstrap

问题描述

基本上，我可以将Bootstrap 3.3.4中导航栏的背景颜色更改为我想要的任何颜色，只需使用以下命令即可： 

.navbar {background-color: whatever color I want;}

除了当我想使用以下方法删除颜色时： 

.navbar {background-color: transparent;}

我已经尝试了多种方法来完成此操作，并且在引导程序的早期版本中效果很好，这是一个已知问题，还是有一个新类使导航栏中的背景透明？

有两种解决方法：

  • 更改body background-color 。 使页面的主体透明将使基础图像可见。 默认情况下，主体具有白色的背景色。 

     html { background: url(http://cdn.wonderfulengineering.com/wp-content/uploads/2014/10/simple-wallpaper-26.jpg)no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } body { background-color: rgba(0, 0, 0, 0) !important; /*by default white*/ } .navbar { background-color: transparent !important; } /*just to put emphasis on the changes*/ /*.container-fluid { border-bottom: solid; } */ a { color: black !important; } 
     <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script> <nav class="navbar navbar-default"> <div class="container-fluid"> <!-- Brand and toggle get grouped for better mobile display --> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <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> <!-- Collect the nav links, forms, and other content for toggling --> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a> </li> <li><a href="#">Link</a> </li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a> </li> <li><a href="#">Another action</a> </li> <li><a href="#">Something else here</a> </li> <li class="divider"></li> <li><a href="#">Separated link</a> </li> <li class="divider"></li> <li><a href="#">One more separated link</a> </li> </ul> </li> </ul> <form class="navbar-form navbar-left" role="search"> <div class="form-group"> <input type="text" class="form-control" placeholder="Search"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> <ul class="nav navbar-nav navbar-right"> <li><a href="#">Link</a> </li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a> </li> <li><a href="#">Another action</a> </li> <li><a href="#">Something else here</a> </li> <li class="divider"></li> <li><a href="#">Separated link</a> </li> </ul> </li> </ul> </div> <!-- /.navbar-collapse --> </div> <!-- /.container-fluid --> </nav>

要么

  • 而不是在html标签上使用background属性，而是将其放在页面正文中。 

     body { background: url(http://cdn.wonderfulengineering.com/wp-content/uploads/2014/10/simple-wallpaper-26.jpg)no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } .navbar { background-color: transparent !important; } /*just to put emphasis on the changes*/ /*.container-fluid { border-bottom: solid; } */ a { color: black !important; } 
     <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script> <nav class="navbar navbar-default"> <div class="container-fluid"> <!-- Brand and toggle get grouped for better mobile display --> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <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> <!-- Collect the nav links, forms, and other content for toggling --> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a> </li> <li><a href="#">Link</a> </li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a> </li> <li><a href="#">Another action</a> </li> <li><a href="#">Something else here</a> </li> <li class="divider"></li> <li><a href="#">Separated link</a> </li> <li class="divider"></li> <li><a href="#">One more separated link</a> </li> </ul> </li> </ul> <form class="navbar-form navbar-left" role="search"> <div class="form-group"> <input type="text" class="form-control" placeholder="Search"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> <ul class="nav navbar-nav navbar-right"> <li><a href="#">Link</a> </li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a> </li> <li><a href="#">Another action</a> </li> <li><a href="#">Something else here</a> </li> <li class="divider"></li> <li><a href="#">Separated link</a> </li> </ul> </li> </ul> </div> <!-- /.navbar-collapse --> </div> <!-- /.container-fluid --> </nav>


第二种选择更可取。
忽略添加到属性.container-fluid类和a元件，它们的存在只是为了进行更改更加明显。
