Question

我正在制作一个简单网站的教程，当我尝试运行bootstrap模板时，它似乎没有出现

我已经包含了bootstrap.js文件以及jquery，这里是我的代码：

<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet" href="/css/bootstrap.css">
<script src ="jquery-3.2.1.min.js"></script>
<script src="bootstrap.min.js"></script>
</head>
<body>

<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
        <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="#">Kevo's Website</a>
    </div>
    <div id="navbar" class="collapse navbar-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="index.html">Home</a></li>
        <li><a href="about.html">About</a></li>
        <li><a href="services.html">Services</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>
</nav>

<div class="container">

    <div class="row">
    <h1>Welcome</h1>
        <p>This is the welcome page</p>
    </div>

</div><!-- /.container -->

</body>
</html>

Answer 1

从您的屏幕截图中，我猜测/css/bootstrap.css正在返回404，或者您正在使用浏览器从文件系统加载HTML的功能（通过双击index.html文件），在这种情况下，引用/css/bootstrap.css正在根驱动器中查找路径为/css/bootstrap.css的文件夹。如果你有css文件int他在同一文件夹中只需删除/css/它就可以了。

对我来说很好看。正如Jason所说，我认为你的本地引导文件没有被正确调用。

.row {
  margin-top: 50px;
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
        <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="#">Kevo's Website</a>
    </div>
    <div id="navbar" class="collapse navbar-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="index.html">Home</a></li>
        <li><a href="about.html">About</a></li>
        <li><a href="services.html">Services</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>
</nav>

<div class="container">

  <div class="row">
    <h1>Welcome</h1>
    <p>This is the welcome page</p>
  </div>

</div><!-- /.container -->

看起来您的css / boostrap没有正确链接，如果您在本地计算机上执行此操作尝试view source并单击其中的css路径。并且必须在body标签结束之前放置jquery和boostrap.js。
