问题:

删除Bootstrap 3中col-md- *右侧和左侧的填充/边距。

HTML code:

<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,此代码在两列的右侧和左侧添加了填充/边距。我想知道为了消除两边多余的空间我错过了什么?

注意:

如果我删除“col-md-4”,则两列都会扩展到100%,但我希望它们彼此相邻。

您通常使用.row来包装两列,而不是.col-md-12 - 这是一个包含另一列的列。毕竟,.row没有col-md-12带来的额外边距和填充,并且还会折叠列将带有负左和下的空间。右边距。

<div class="container">
    <div class="row">
        <h2>OntoExplorer<span style="color:#b92429">.</span></h2>

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

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

如果确实想要删除填充/边距,请添加一个类来过滤掉每个子列的边距/填充。

.nopadding {
   padding: 0 !important;
   margin: 0 !important;
}

答案 1 :(得分:166)

我总是将这种风格添加到我的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">

如果您只想定位子列,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;
}

您可能还想删除某些设备尺寸的填充(SASS示例):

/* 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;
    }
  }
}

如果您希望它向上支持小型设备,则可以删除媒体查询的最大宽度部分。

答案 2 :(得分:43)

减少列上的填充不会成功,因为你会扩展页面的宽度,使其与页面的其余部分不一致,比如navbar。您需要同样减少行上的负边距。以@ martinedwards&#39;更少的例子:

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

答案 3 :(得分:22)

特别针对SASS mixin:

@mixin no-padding($side) {
    @if $side == 'all' {
        .no-padding {
            padding: 0 !important;
        }
    } @else {
        .no-padding-#{$side} {
            padding-#{$side}: 0 !important;
        }
    }
}

@include no-padding("left");
@include no-padding("right");
@include no-padding("top");
@include no-padding("bottom");
@include no-padding("all");

然后在HTML中,您可以使用

.no-padding-left
.no-padding-right
.no-padding-bottom
.no-padding-top
.no-padding - to remove padding from all sides

当然,你只能@include那些你需要的声明。

只需添加“no-padding”,这是bootstrap 3中的内置类

答案 5 :(得分:12)

此后仅适用于Bootstrap4

<div class="p-0 m-0">
</div>

注意:.p-0和.m-0已添加bootstrap.css

答案 6 :(得分:10)

另一种解决方案,只有在从LESS源编译bootstrap时才可行,是重新定义设置列填充的变量。

您会在variables.less文件中找到该变量:它名为@grid-gutter-width

它在消息来源中描述如下:

//** Padding between columns. Gets divided in half for the left and right.
@grid-gutter-width:         30px;

将此项设置为0,编译bootstrap.less,并包含生成的bootstrap.css。你完成了。如果您已经使用像我这样的引导源,它可以是定义附加规则的替代方法。

Bootstrap 4 有一个本机类来执行此操作:将类.no-gutters添加到父.row

答案 8 :(得分:6)

[class*="col-"]
  padding: 0
  margin: 0

答案 9 :(得分:3)

Bootstrap 4 has the class .no-gutters that you can add to the row element.

<div class="container-fluid">
    <div class="row no-gutters">
        <div class="col-md-12">
            [YOUR CONTENT HERE]
        </div>
    </div>
</div>

以上解决方案都不适合我。在this answer之后,我能够创造出适合我的东西。在这里,我也使用媒体查询将其限制为仅限小屏幕。

@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;
    }
}

我想使用

更容易
margin:-30px;

覆盖bootstrap设置的原始值。

我试过

margin: 0px -30px 0px -30px;

您可以在col-md-4内的div中添加一行行,并且行的-15px边距将平衡列中的装订线。关于Bootstrap 3中的排水沟和排的好解释here

使用3.7.7以下的引导程序删除黑白列的间距。

  

.no-gutter是一个自定义类,您可以将其添加到行DIV中

.no-gutter > [class*='col-'] {
        padding-right:0;
        padding-left:0;

将你的专栏包裹在.row中,然后在该div中添加一个名为“no-gutter”的课程

<div class="container">
  <div class="row no-gutter">
    <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">
            </div>
        </div>
    </div>

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

然后将下面的内容粘贴到您的CSS文件

.row.no-gutter {
  margin-left: 0;
  margin-right: 0;
}

.row.no-gutter [class*='col-']:not(:first-child),
.row.no-gutter [class*='col-']:not(:last-child) {
  padding-right: 0;
  padding-left: 0;
}

有时您可能会丢失列所需的填充。他们最终坚持彼此。为了防止这种情况,您可以按如下方式更新类:

<div class="col-md-3 NoPaddingForChildren">
        <div class="col-md-6">
                    <label>Id</label>
                    <input ng-model="ID" class="form-control">
        </div>

建立Vitaliy Silin's answer。不仅包括我们根本不需要填充的情况,还包括我们有标准尺寸填充的情况。

See the live conversion of this code to CSS on sassmeister.com

@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;
}

您可以使用bootstrap创建Less Mixins来管理列的边距和填充,例如

http://mohandere.work/less-mixins-for-margin-and-padding-with-bootstrap-3/

用法:

xs-padding-lr-15px//left right both
xs-padding-l-15px 
xs-padding-r-15px

类似于设置保证金/填充零,您可以使用

xs-padding-lr-0px
xs-padding-l-0px
xs-padding-r-0px
