【问题描述】：

如果引导程序可用于设置简单布局，我不想添加任何额外的 CSS 工作。有一个水平滚动。为什么？如果有人知道确切的解决方案，或者我遗漏了什么。请告诉我

【解决方案1】：

在html 的body 中使用container 或container-fluid

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

  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<div class="jumbotron text-center">
  <h1>My First Bootstrap Page</h1>
  <p>Resize this responsive page to see the effect!</p> 
</div>
  

  <div class="row">
    <div class="col-sm-4">
      <h3>Column 1</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit...</p>
      <p>Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris...</p>
    </div>
    <div class="col-sm-4">
      <h3>Column 2</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit...</p>
      <p>Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris...</p>
    </div>
    <div class="col-sm-4">
      <h3>Column 3</h3>        
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit...</p>
      <p>Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris...</p>
    </div>
  </div>
 </div>

我只想要端到端。
如果你想无边距显示你的内容，那么使用container-fluid class <div class="container-fluid"> Your content..... </div>
容器流体类本身有填充。
与container-fluid 一起使用一个类p-0，这将不提供填充。 <div class="container-fluid p-0"> Your content..... </div>
谢谢，但我需要在内部 div 中添加 m-0 类。这是个好主意。
