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。

以Vitaliy Silin的回答为基础。不仅包括我们根本不需要填充的情况,还包括我们有标准大小填充的情况。

在sassmeister.com上查看此代码到CSS的实时转换

@mixin padding($side, $size) {
    $padding-size : 0;
    @if $size == 'xs' { $padding-size : 5px; }
    @else if $size == 's' { $padding-size : 10px; }
    @else if $size == 'm' { $padding-size : 15px; }
    @else if $size == 'l' { $padding-size : 20px; }

    @if $side == 'all' {
        .padding--#{$size} {
            padding: $padding-size !important;
        }
    } @else {
        .padding-#{$side}--#{$size} {
            padding-#{$side}: $padding-size !important;
        }
    }
}

$sides-list: all top right bottom left;
$sizes-list: none xs s m l;
@each $current-side in $sides-list {
  @each $current-size in $sizes-list {
    @include padding($current-side,$current-size);
  }
}

然后输出:

.padding--none {
  padding: 0 !important;
}

.padding--xs {
  padding: 5px !important;
}

.padding--s {
  padding: 10px !important;
}

.padding--m {
  padding: 15px !important;
}

.padding--l {
  padding: 20px !important;
}

.padding-top--none {
  padding-top: 0 !important;
}

.padding-top--xs {
  padding-top: 5px !important;
}

.padding-top--s {
  padding-top: 10px !important;
}

.padding-top--m {
  padding-top: 15px !important;
}

.padding-top--l {
  padding-top: 20px !important;
}

.padding-right--none {
  padding-right: 0 !important;
}

.padding-right--xs {
  padding-right: 5px !important;
}

.padding-right--s {
  padding-right: 10px !important;
}

.padding-right--m {
  padding-right: 15px !important;
}

.padding-right--l {
  padding-right: 20px !important;
}

.padding-bottom--none {
  padding-bottom: 0 !important;
}

.padding-bottom--xs {
  padding-bottom: 5px !important;
}

.padding-bottom--s {
  padding-bottom: 10px !important;
}

.padding-bottom--m {
  padding-bottom: 15px !important;
}

.padding-bottom--l {
  padding-bottom: 20px !important;
}

.padding-left--none {
  padding-left: 0 !important;
}

.padding-left--xs {
  padding-left: 5px !important;
}

.padding-left--s {
  padding-left: 10px !important;
}

.padding-left--m {
  padding-left: 15px !important;
}

.padding-left--l {
  padding-left: 20px !important;
}

其他回答

你可以创建一个新的类来删除边距,并应用于你想要删除额外边距的元素:

.margL0 { margin-left:0 !important }

重要:它将帮助您删除默认的保证金或覆盖当前的保证金值

并应用于您想要从左侧删除边缘的div

简单地添加“无填充”,这是bootstrap 3的内置类

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">
<h2>OntoExplorer<span style="color:#b92429">.</span></h2>

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

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