我正在使用CodePen开发一个项目,我正在使用bootstrap创建一个导航栏。但由于某种原因,它是垂直显示而不是水平显示。即使我复制并粘贴了W3Schools示例和Bootstrap website中的代码。我不知道还能做什么。请帮忙。
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#">WebSiteName</a>
</div>
<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>
<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" 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>
<!-- 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-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
<form class="navbar-form navbar-left">
<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-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
两者都不起作用。是的,我已经对我的<link>
和<script>
代码进行了三次检查。

首先,在评论中你使用bootstrap 3标记并且你链接到bootstrap 3和4删除bootstrap 4 css。然后你需要使用collapse navbar-collapse
类的div,所以只需将其添加到id为nav
的div中,如下所示:
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#about">
<span style="font-family: 'Source Code Pro', Monospace; color:green"><i class="fa fa-code"></i>Ryan</span></a>
</div>
<div class="collapse navbar-collapse" id="nav">
<ul class="nav navbar-nav">
<li><a href="#about">About</a></li>
<li><a href="#portfolio">Portfolio</a></li>
<li><a href="#contact">Contact</a></li>
</ul>
</div>
</div>
</nav>
您可能希望将折叠按钮添加到导航栏标题中,否则您的链接将不会显示在移动设备宽度上,因此它看起来像:
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#nav" 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="#about">
<span style="font-family: 'Source Code Pro', Monospace; color:green"><i class="fa fa-code"></i>Ryan</span>
</a>
</div>
<div class="collapse navbar-collapse" id="nav">
<ul class="nav navbar-nav">
<li><a href="#about">About</a></li>
<li><a href="#portfolio">Portfolio</a></li>
<li><a href="#contact">Contact</a></li>
</ul>
</div>
</div>
</nav>

正如有人所说 - 从加载的CSS文件中删除bootstrap 4并且它将起作用
