【问题描述】：

在 bootstrap 3.3.6 版本的 dist 文件夹中，我有一个 index.html 文件，其中包含以下代码，但这些代码不起作用。使用 bootstrap 文件夹，我们有 cs、js、font 文件夹和 index.html

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
  <title>Bootstrap 101 Template</title>

  <!-- Bootstrap -->
  <link href="css/bootstrap.min.css" rel="stylesheet">

  <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
  <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->

  <script src="js/bootstrap.min.js"></script>
</head>

<body>
  <!--h1 class="text-primary">Hello, world!</h1-->
  <div class="container">
    <div class="row">
      <div class="col-mid-4">Left Side </div>
      <div class="col-mid-4">Middle</div>
      <div class="col-mid-4">Left Side </div>
    </div>

  </div>


</body>

</html>

【问题讨论】：

请检查css路径是否有问题

标签： jquery html css twitter-bootstrap twitter-bootstrap-3

【解决方案1】：

使用col-md-* 而不是mid

<link href="css/bootstrap.min.css" rel="stylesheet">
<script src="js/jquery/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<div class="container">
  <div class="row">
     <div class="col-md-4">Left Side </div>
     <div class="col-md-4">Middle</div>
     <div class="col-md-4">Left Side </div>
   </div>
</div>

解决办法如下：

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
  <title>Bootstrap 101 Template</title>

  <!-- Bootstrap -->
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script></head>

<body>
  <!--h1 class="text-primary">Hello, world!</h1-->
  <div class="container">
    <div class="row">
      <div class="col-xs-4 col-md-4 col-sm-4 col-lg-4">Left Side </div>
      <div class="col-xs-4 col-md-4  col-sm-4 col-lg-4">Middle</div>
      <div class="col-xs-4 col-md-4 col-sm-4 col-lg-4">Left Side </div>
    </div>

  </div>


</body>

</html>
