我正在使用默认布局和扩展它的另一个模板。我正在试用 mdb bootstrap 免费版，但它运行不正常。我认为在 head-layouts 文件中链接有问题。我也试过在本地安装但也没有用。也许我在这里遗漏了一些基本的东西。
布局:
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>dataMS</title>
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon">
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
<link href="styles/site.css" rel="stylesheet"/>
</head>
模板扩展布局-
<div id="carousel-example-2" class="carousel slide carousel-fade" data-ride="carousel">
<!--Indicators-->
<ol class="carousel-indicators">
<li data-target="#carousel-example-2" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-2" data-slide-to="1"></li>
<li data-target="#carousel-example-2" data-slide-to="2"></li>
</ol>
<!--/.Indicators-->
<!--Slides-->
<div class="carousel-inner" role="listbox">
<div class="carousel-item active">
<div class="view hm-black-light">
<img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(68).jpg" alt="First slide">
<div class="mask"></div>
</div>
<div class="carousel-caption">
<h3 class="h3-responsive">Light mask</h3>
<p>First text</p>
</div>
</div>
<div class="carousel-item">
<!--Mask color-->
<div class="view hm-black-strong">
<img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(6).jpg" alt="Second slide">
<div class="mask"></div>
</div>
<div class="carousel-caption">
<h3 class="h3-responsive">Strong mask</h3>
<p>Secondary text</p>
</div>
</div>
<div class="carousel-item">
<!--Mask color-->
<div class="view hm-black-slight">
<img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(9).jpg" alt="Third slide">
<div class="mask"></div>
</div>
<div class="carousel-caption">
<h3 class="h3-responsive">Slight mask</h3>
<p>Third text</p>
</div>
</div>
</div>
<!--/.Slides-->
<!--Controls-->
<a class="carousel-control-prev" href="#carousel-example-2" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carousel-example-2" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>

最佳答案
您使用的是 Bootstrap 3，而 MDB 基于 Bootstrap 4。B4 不向后兼容 Bootstrap 3，因此它不会工作。从这里下载新包: https://mdbootstrap.com/getting-started/
放置您的代码，它将起作用。我刚刚测试过它。
关于css - MDB Bootstrap 无法正常运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46930046/
