html - 如何使引导示例全宽

问题描述

我为在线网站所需的时间线找到了这段代码。您可以在https://jsfiddle.net/中查看它的外观。我的问题是为什么它这么小？我在 css 中没有看到任何设置大小的内容，这是引导功能吗？

代码也贴在下面：

<head>
<link href="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">
<script src="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>

<body>
<div class="container mt-5 mb-5">
<div class="row">
<div class="col-md-6 offset-md-3">
<h4>Latest News</h4>
<ul class="timeline">
<li>
<a target="_blank" href="https://www.totoprayogo.com/#">New Web Design</a>
<a href="#" class="float-right">21 March, 2014</a>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque scelerisque diam non nisi semper, et elementum lorem ornare. Maecenas placerat facilisis mollis. Duis sagittis ligula in sodales vehicula....</p>
</li>
<li>
<a href="#">21 000 Job Seekers</a>
<a href="#" class="float-right">4 March, 2014</a>
<p>Curabitur purus sem, malesuada eu luctus eget, suscipit sed turpis. Nam pellentesque felis vitae justo accumsan, sed semper nisi sollicitudin...</p>
</li>
<li>
<a href="#">Awesome Employers</a>
<a href="#" class="float-right">1 April, 2014</a>
<p>Fusce ullamcorper ligula sit amet quam accumsan aliquet. Sed nulla odio, tincidunt vitae nunc vitae, mollis pharetra velit. Sed nec tempor nibh...</p>
</li>
</ul>
</div>
</div>
</div>
</body>

CSS：

ul.timeline {
    list-style-type: none;
    position: relative;
}
ul.timeline:before {
    content: ' ';
    background: #d4d9df;
    display: inline-block;
    position: absolute;
    left: 29px;
    width: 2px;
    height: 100%;
    z-index: 400;
}
ul.timeline > li {
    margin: 20px 0;
    padding-left: 20px;
}
ul.timeline > li:before {
    content: ' ';
    background: white;
    display: inline-block;
    position: absolute;
    border-radius: 50%;
    border: 3px solid #22c0e8;
    left: 20px;
    width: 20px;
    height: 20px;
    z-index: 400;
}

感谢您的帮助，您可以说我不是最好的开发人员，但我真的很想在我的网站上添加此功能。

解决方案

您应该将 div 的类从“.col-md-6, .offset-md-3”更改为“.col-12”，如果还不够，则将“.container”更改为“.container-fluid” .

<body>
  <div class="container-fluid mt-5 mb-5">
    <div class="row">
      <div class="col-12">
        <h4>Latest News</h4>
          <ul class="timeline">
          <li>
            <a target="_blank" href="https://www.totoprayogo.com/#">New Web Design</a>
            <a href="#" class="float-right">21 March, 2014</a>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque scelerisque diam non nisi semper, et elementum lorem ornare. Maecenas placerat facilisis mollis. Duis sagittis ligula in sodales vehicula....</p>
          </li>
          <li>
            <a href="#">21 000 Job Seekers</a>
            <a href="#" class="float-right">4 March, 2014</a>
             <p>Curabitur purus sem, malesuada eu luctus eget, suscipit sed turpis. Nam pellentesque felis vitae justo accumsan, sed semper nisi sollicitudin...</p>
          </li>
          <li>
            <a href="#">Awesome Employers</a>
            <a href="#" class="float-right">1 April, 2014</a>
            <p>Fusce ullamcorper ligula sit amet quam accumsan aliquet. Sed nulla odio, tincidunt vitae nunc vitae, mollis pharetra velit. Sed nec tempor nibh...</p>
           </li>
       </ul>
     </div>
   </div>
  </div>
</body>
