html - 如何在没有列填充的情况下为 Bootstrap 行的背景着色？

Question

我试图使背景适合引导程序的列大小，但仍然出现在整行中。我怎么能做到这一点？

我尝试了以下方法：

.yourcontent {
  margin-bottom: 5px;
}

.yourcontent [class^=col-] {
  background-color: cyan;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">

  <div class="row">
    <div class="col-xs-12">
      <div class="btn-group" role="group" style="margin-top: 5px; margin-bottom: 5px">
        <button type="button" class="btn btn-primary">Foo</button>
        <button type="button" class="btn btn-primary">Bar</button>
        <button type="button" class="btn btn-primary">Foobar</button>
        <button type="button" class="btn btn-primary">Barfoo</button>
      </div>
    </div>
  </div>

  <div class="row">
    <div class="col-xs-12">

      <div class="row yourcontent">
        <div class="col-xs-6">
          <div class="">
            Foo
          </div>
        </div>
        <div class="col-xs-2">
          <div class="">
            Bar
          </div>
        </div>
        <div class="col-xs-2">
          <div class="">
            Foobar
          </div>
        </div>
        <div class="col-xs-2">
          <div class="">
            Barfoo
          </div>
        </div>
      </div>

    </div>

  </div>
</div>

JSFiddle

我希望它看起来像这样，除了列之间的空白也应该用颜色填充：

.yourcontent {
  margin-bottom: 5px;
  background-color: cyan;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">

  <div class="row">
    <div class="col-xs-12">
      <div class="btn-group" role="group" style="margin-top: 5px; margin-bottom: 5px">
        <button type="button" class="btn btn-primary">Foo</button>
        <button type="button" class="btn btn-primary">Bar</button>
        <button type="button" class="btn btn-primary">Foobar</button>
        <button type="button" class="btn btn-primary">Barfoo</button>
      </div>
    </div>
  </div>

  <div class="row">
    <div class="col-xs-12">

      <div class="row">
        <div class="col-xs-6">
          <div class="yourcontent">
            Foo
          </div>
        </div>
        <div class="col-xs-2">
          <div class="yourcontent">
            Bar
          </div>
        </div>
        <div class="col-xs-2">
          <div class="yourcontent">
            Foobar
          </div>
        </div>
        <div class="col-xs-2">
          <div class="yourcontent">
            Barfoo
          </div>
        </div>
      </div>

    </div>

  </div>
</div>

JSFiddle

我希望背景拉伸整行，而不是第一个 col-xs-* 元素的 padding-left 和给定行中最后一个 col-xs-* 元素的 padding-right。有人会碰巧知道如何解决这个问题吗？

在Bootstrap 4中你有这个.no-gutters类。由于您使用的是Bootstrap 3，因此不包括此类。但是，您可以自己轻松地创建此类。这将删除列之间的排水沟。

.yourcontent {
  margin-bottom: 5px;
  background-color: cyan;
}

/* 
  Optional, to fix to width of the row 
*/
.row.no-gutters {
  margin-left: 0;
  margin-right: 0;
}


.row.no-gutters > [class^="col-"] {
  padding-left: 0;
  padding-right: 0;
}
