Bootstrap 4行扩展到容器

标签： html twitter-bootstrap bootstrap-4 twitter-bootstrap-4

我正在为我的老板开发一个简单的网站。我决定尝试使用bootstrap并选择版本4.所以我有一个非常好的模板结构化，并注意到主要内容的行延伸超出容器div的范围。它是页面上唯一可以执行此操作的行。我尝试用任何一个/两个元素上的边距或填充来改变间距，它似乎没有改变任何东西。我还尝试在section标签内包含主要内容，因为其他两行包含在页眉/页脚标签中，并且它们仍然在边界内。这也行不通。我可能遗漏了一些明显的东西。感谢您的帮助，我很感激。

我突出显示容器只是为了显示它的边界框。我也在这个屏幕截图中删除了填充，但无论如何都是同样的问题。

引导程序中的.row左右为-15px，用内联样式覆盖它=＆＃34; margin：auto＆＃34;你会没事的。

旁边有一个默认的左右填充15，所以在你的情况下你应该将padding-left设置为0，使内容适合网格。

<section id="page-content">
  <div class="row" style="margin: auto">
    <aside class="col-md-3" style="padding-left: 0">
      <div class="card mt-3">
        <a href="#">
          <img class="card-img-top" src="http://via.placeholder.com/200x200" alt="Card image cap">
          <div class="card-body">
            <p class="card-text">Service</p>
          </div>
        </a>
      </div>

      <div class="card mt-3">
        <a href="#">
          <img class="card-img-top" src="http://via.placeholder.com/200x200" alt="Card image cap">
          <div class="card-body">
            <p class="card-text">Products</p>
          </div>
        </a>
      </div>

      <div class="card mt-3">
        <a href="#">
          <img class="card-img-top" src="http://via.placeholder.com/200x200" alt="Card image cap">
          <div class="card-body">
            <p class="card-text">Parts & accessories</p>
          </div>
        </a>
      </div>
    </aside>

    <article class="main col-md-9 col-sm-12 px-3 mt-3">
      <p>This is the main content area</p>

  </div><!--END ROW-->

答案 1 :(得分：3)

使用班级<div class="container"> <ul> <li> Row 1 Loooooooooooooooooooooooooooooooong content <div class="button">Btn 1</div> </li> <li> Row 2 short content <div class="button">Btn 2</div> </li> </ul> </div>而不是{4}启动4道。

答案 2 :(得分：0)

在引导程序的4行中添加“禁止插入”也是摆脱边距和填充的好方法。

  

我们预定义的网格类中各列之间的装订线可以是   用.no-gutters删除。这将消除.row中的负边距   以及所有直接子级列的水平填充。

答案 3 :(得分：0)

考虑到以上答案，有时您需要在项目中编辑默认CSS属性。 因此，如果您想应用no-gutters或任何CSS属性，只需在主 CSS / SASS 文件上更改该属性，如下所示：

.row {
    margin: 0;
}

此hack将删除项目中所有行的无余裕！

答案 4 :(得分：0)

将 mx-0 添加到溢出元素将解决您的问题。
