从Bootstrap 3中的列中删除填充-Java 学习之路

293

Problem:

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>

Desired output:

目前，此代码在两列的右侧和左侧添加填充/边距 . 我想知道为了消除侧面的这个额外空间我错过了什么？

Notice:

如果我删除“col-md-4”，那么两列都会扩展到100％，但我希望它们彼此相邻 .

减少列上的填充不会成为诀窍，因为你将扩展页面的宽度，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为例：
```
.row-no-padding {
  margin-left: 0;
  margin-right: 0;
  [class*="col-"] {
    padding-left: 0 !important;
    padding-right: 0 !important;
  }
}
```

我想这更容易使用
```
margin:-30px;
```
覆盖bootstrap设置的原始值 .

我试过了
```
margin: 0px -30px 0px -30px;
```
它对我有用 .

您可以创建一个用于删除边距的新类，并且可以应用于要删除额外边距的元素：
```
.margL0 { margin-left:0 !important }
```
!important ：它将帮助您删除默认边距或覆盖当前边距值

并应用于您要从左侧删除边距的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，我还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;
    }
}

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右边距的空间 .

<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>

如果您确实想要删除填充/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;
}

You can create Less Mixins using bootstrap for manage margins and paddings of your columns like,

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

Usage:
```
xs-padding-lr-15px//left right both
xs-padding-l-15px 
xs-padding-r-15px
```
类似地设置margin / padding零，你可以使用，
```
xs-padding-lr-0px
xs-padding-l-0px
xs-padding-r-0px
```

将您的列包装在.row中，并在该div中添加一个名为“no-gutter”的类

<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CSS文件中

.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;
}

特别适用于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你需要的那些声明 .

您可以自定义Bootstrap网格系统并定义自定义响应网格 .

将以下装订线宽度的默认值从 @grid-gutter-width = 30px 更改为 @grid-gutter-width = 0px

（装订线宽度是列之间的填充 . 左右分为两半 . ）

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;
    }
  }
}

如果您希望媒体查询向上支持小型设备，则可以删除该媒体查询的最大宽度部分 .

Bootstrap具有可以添加到row元素的类.no-gutters .
```
<div class="container-fluid">
    <div class="row no-gutters">
        <div class="col-md-12">
            [YOUR CONTENT HERE]

有时您可能会丢失列所需的填充 . 他们最终坚持彼此 . 为防止这种情况，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>
        <div class="col-md-6">
                    <label>Value</label>
                    <input ng-model="Val" class="form-control">
        </div>
</div>

和相应的类：

.NoPaddingForChildren > div:not(:first-child):not(:last-child) {
    padding-left: 0;
    padding-right: 0;
}

.NoPaddingForChildren > div:first-child {
    padding-left: 0;
}

.NoPaddingForChildren > div:last-child {    
    padding-right: 0;
}

Build Vitaliy Silin's answer . 不仅涵盖我们根本不需要填充的情况，还覆盖我们有标准尺寸衬垫的情况 .

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：

另一个解决方案，只有从LESS源编译bootstrap时才可行，是重新定义设置列填充的变量 .

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

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;
```
将此值设置为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 .

使用bootstrap 3.7.7或更低版本从b / w列中删除间距 .

.no-gutter是一个自定义类
```
.no-gutter > [class*='col-'] {
        padding-right:0;
        padding-left:0;
    }
```

<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中添加一类行，并且行的-15px边距将 balancer 列中的装订线 . 关于Bootstrap 3中的排水沟和排的好解释here .

如果您使用SASS文件下载bootstrap，您将能够编辑配置文件，其中有一个列的边距设置，然后保存它，这样SASS计算列的新宽度

只需在bootstrap中添加 "no-padding" 这是内置类

此后仅在Bootstrap4上提供
```
<div class="p-0 m-0">
</div>
```
注意：.p-0和.m-0已经添加了bootstrap.css
