问题:

在引导3中删除col-md-*的左右边距。

HTML代码:

<div class="col-md-12">
    <h2>OntoExplorer<span style="color:#b92429">.</span></h2>

    <div class="col-md-4">
        <div class="widget">
            <div class="widget-header">
                <h3>Dimensions</h3>
            </div>

            <div class="widget-content" id="">
                <div id='jqxWidget'>
                    <div style="clear:both;margin-bottom:20px;" id="listBoxA"></div>
                    <div style="clear:both;" id="listBoxB"></div>

                </div>
            </div>
        </div>
    </div>

    <div class="col-md-8">
        <div class="widget">
            <div class="widget-header">
                <h3>Results</h3>
            </div>

            <div class="widget-content">
                <div id="map_canvas" style="height: 362px;"></div>
            </div>
        </div>
    </div>

</div>

期望的输出:

目前,这段代码在两列的右侧和左侧添加了填充/边距。我在想,为了去掉两边的多余空间,我错过了什么?

注意:

如果我删除“col-md-4”,那么两列展开到100%,但我希望它们彼此相邻。


当前回答

Bootstrap 4有一个原生类来做这件事:将类.no-gutters添加到父类.row

其他回答

Bootstrap 4添加了.no-gutters类。

Bootstrap 3.4添加了.row-no-gutters类

Bootstrap 3:我总是把这个风格添加到我的Bootstrap LESS / SASS:

.row-no-padding {
  [class*="col-"] {
    padding-left: 0 !important;
    padding-right: 0 !important;
  }
}

然后在HTML中你可以写:

<div class="row row-no-padding">

如果你只想瞄准子列,你可以使用子选择器(感谢John Wu)。

.row-no-padding > [class*="col-"] {
    padding-left: 0 !important;
    padding-right: 0 !important;
}

你也可以只移除某些设备尺寸的填充(例如SASS):

/* Small devices (tablets, 768px and up) */
@media (min-width: $screen-sm-min) and (max-width: $screen-sm-max) {
  .row-sm-no-padding {
    [class*="col-"] {
      padding-left: 0 !important;
      padding-right: 0 !important;
    }
  }
}

如果您希望媒体查询向上支持小型设备,可以删除媒体查询的max-width部分。

以上的解决方案都不适合我。根据这个答案,我能够创造一些适合我的东西。在这里,我还使用了一个媒体查询,以限制这只小屏幕。

@media (max-width: @screen-sm) {
    [class*="col-"] {
      padding-left: 0;
      padding-right: 0;
    }
    .row {
      margin-left: 0;
      margin-right: 0;
    }
    .container-fluid {
      margin: 0;
      padding: 0;
    }
}

Bootstrap 4有一个原生类来做这件事:将类.no-gutters添加到父类.row

<div class="col-md-12">

            </div>

您可以在col-md-4内的div中添加一个类row,行的-15px边缘将平衡列的沟槽。在Bootstrap 3中关于水槽和排的很好的解释。
