Question

我正在尝试学习自适应网站的引导程序基础知识。当我将元素放入“行”类中时，这些元素没有任何边距或填充，也没有可用空间，但是使用jumbotron和navbar这样的元素，则似乎存在填充，我无法摆脱它的左侧和右边。任何帮助将不胜感激。

<nav class="navbar navbar-expand-lg navbar-expand-md">
    <a class="navbar-brand" href="#">lorem ipsum</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item">
              <a class="nav-link" href="#">home</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">about</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">contact</a>
            </li>
        </ul>
      </div>
  </nav>
  <div class="jumbotron jumbotron-fluid" style="background-image:url(images/hero-image.jpg)">
    <div class="container-fluid">
        <h1 class="display-4">lorem ipsum</h1>
        <p class="lead">lorem ipsum</p>
      </div>
  </div>
  <div class="row newsletter">
      <p class="col-lg-6 col-md-6 col-sm-6 col-xs-12">subscribe to our newsletter</p>
    <form class="col-lg-6 col-md-6 col-sm-6 col-xs-12 newsForm">
        <input type="email" placeholder="enter your email..." class="box">
        <button type="submit" class="button">></button>
      </form>
  </div>

Answer 1

Boostrap默认情况下在导航栏上应用填充，您只需执行以下操作即可删除左右填充：

String s = "Half Bone-in Spiral int with dark Packd Smithfield Half Bone-in Spiral Ham with Glaze Pack";
String[] res = splitIncludeDelimeter("(\\b.{1,32}(?![\\w-])\\W?)", s);
System.out.println(Arrays.toString(res));
// => [Half Bone-in Spiral int with , dark Packd Smithfield Half , Bone-in Spiral Ham with Glaze , Pack, ]

在.navbar.custom-navbar { padding-left: 0rem !important; padding-right: 0rem !important; }元素上应用custom-navbar类。

要删除jumbotron的左右填充，请删除jumbotron内部的<nav>：

<div class="container-fluid">

也可以从页面上移除水平滚动，将<div class="jumbotron jumbotron-fluid" style="background-image:url(images/hero-image.jpg)"> <h1 class="display-4">odtom.com</h1> <p class="lead">a site showcasing everything odt.</p> </div>放在row内。

我不确定这是否可以回答您的问题，但是jumbotron元素中的左侧和右侧填充来自“ .container-fluid”类。看来您的目标容器是“ .jumbotron-fluid”类，该类当前设置为padding-left，right设置为0px。

仅在需要该类时将其定位为删除或修改填充。

.container-fluid {
   width: 100%;
   padding-right: 15px;
   padding-left: 15px;
   margin-right: auto;
   margin-left: auto;
}

巨型台和导航栏周围的自举填充？
