Bootstrap 4行延伸到容器外部

我正在为我的老板设计一个简单的网站。我决定尝试使用bootstrap，并选择了版本4。所以我有一个非常好的模板结构，并注意到主要内容的行超出了容器div的边界。这是页面上唯一一行这样做。我尝试改变间距与边距或填充的任何一个/两个元素，它似乎没有改变任何东西。我还尝试过将主要内容包含在section标记中，因为其他两行包含在header/footer标记中，并且它们仍然在边界内。这也不起作用。我可能在这里遗漏了一些明显的东西。感谢您的帮助，我很感激。

我突出显示了容器只是为了显示它的边界框。我也有填充从它删除在这个截图中，这是同样的问题，无论哪种方式虽然。

bootstrap中的.row提供的左右边距为-15px，请使用in-line style=“margin：自动”，你应该没事。
aside的默认左填充和右填充都是15，因此在您的情况下，应该将padding-left设置为0，以使内容适合网格。

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

将“no-gutters”类class='row no-gutters'添加到bootstrap 4行中也是一种消除边距和填充的好方法。
在我们预定义的网格类中，列之间的分隔线可以用.no-gutters来删除，这将删除.row中的负边距和所有直接子列中的水平填充。

使用类mr-0代替style="margin-right: 0"，style="margin-right: 0"是 Bootstrap 4路。

将mx-0添加到溢出元素将解决您的问题。

考虑到上述答案，有时你需要编辑默认的CSS属性在您的项目。所以如果你想应用no-gutters或任何CSS属性，你可以简单地改变该属性的主CSS/SASS文件如下：

.row {
    margin: 0;
}

这个黑客将删除所有行在您的项目中的无排水沟保证金！

Bootstrap为行类添加了一个自动的水平间距，所以通过将水平间距（即边距）设置为0来覆盖它，就像;

<div class="row mx-0">
  ....
</div>
