[css] Remove padding from columns in Bootstrap 3

Problem:

Remove padding/margin to the right and left of col-md-* in Bootstrap 3.

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:

Currently this code adds padding/margin to the right and left of the two columns. I am wondering what it is I am missing in order to remove this extra space on the sides?

Notice:

If I remove "col-md-4" then both columns expand to 100% but I want them to be next to each other.

You can customize your Bootstrap Grid system and define your custom responsive grid.

change your default values for the following gutter width from @grid-gutter-width = 30px to @grid-gutter-width = 0px

(Gutter width is padding between columns. It gets divided in half for the left and right.)

Another solution, feasible only if you compile bootstrap from its LESS sources, is to redefine the variable which sets the padding for the columns.

You will find the variable in the variables.less file: it's called @grid-gutter-width.

It's described like this in the sources:

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

Set this to 0, compile bootstrap.less, and include the resulting bootstrap.css. You are done. It can be an alternative to defining an additional rule, if you are already using bootstrap sources like I am.

I guess it's easier to just use

margin:-30px;

to override the original value set by bootstrap.

I've tried

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

and it worked for me.

gem "bootstrap", github: "srghma/bootstrap-rubygem-without-gutter"

None of the above solutions worked perfectly for me. Following this answer I was able to create something that works for me. Here I am also using a media query to limit this to small screens only.

@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;
    }
}

Building up on Vitaliy Silin's answer. Covering not only cases where we do not want padding at all, but also cases where we have standard size paddings.

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);
  }
}

This then outputs:

.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;
}

Bootstrap 4 has a native class to do this : add the class .no-gutters to the parent .row

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

Similarly for setting margin/padding zero you can use,

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

You can create a new class for removing margin and can apply to the element where you want to remove extra margin:

.margL0 { margin-left:0 !important }

!important : it will help you to remove the default margin or overwrite the current margin value

and apply to that div from in which you want to remove the margin from left side

<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>

You can add a class of row to the div inside the col-md-4 and the row's -15px margin will balance out the gutter from the columns. Good explanation here about gutters and rows in Bootstrap 3.

Wrap your columns in a .row and add to that div a class called "no-gutter"

<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>

Then paste below contents to your CSS file

.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;
}

simply Add "no-padding" which is inbuilt class in bootstrap 3

Specifically for 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");

Then in HTML, you can use

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

Sure, you can @include only those declarations, which you need.

Sometimes you might lose the padding that you want for the columns. They end up sticking to each other. To prevent that, you could update the class as follows:

<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>

and corresponding class:

.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;
}

Remove spacing from b/w columns using bootstrap 3.7.7 or less.

.no-gutter is a custom class that you can add to your row DIVs

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

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>

Reference: http://getbootstrap.com/docs/4.0/layout/grid/#grid-options

Bootstrap 4 has added .no-gutters class.

Bootstrap 3.4 has added .row-no-gutters class

Bootstrap 3: I always add this style to my Bootstrap LESS / SASS:

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

Then in the HTML you can write:

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

If you want to only target the child columns you can use the child selector (Thanks John Wu).

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

You may also want to remove padding only for certain device sizes (SASS example):

/* 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;
    }
  }
}

You can remove the max-width part of the media query if you want it to support small devices upwards.

Bootstrap 3, since version 3.4.0, has an official way of removing the padding: the class row-no-gutters.

Example from the documentation:

<div class="row row-no-gutters">
  <div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<div class="row row-no-gutters">
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<div class="row row-no-gutters">
  <div class="col-xs-6">.col-xs-6</div>
  <div class="col-xs-6">.col-xs-6</div>
</div>

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

Hereafter only available at Bootstrap4

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

note: .p-0 and .m-0 already added bootstrap.css

If you download bootstrap with the SASS files you will be able to edit the config file where there are a setting for the margin of the columns and then save it, in that way the SASS calculates the new width of the columns

I still prefer to have control over every padding in every screen size so this css might be usefull to You guys :)

.nopadding-lg {
    padding-left: 0!important;
    padding-right: 0!important;
}
.nopadding-left-lg {padding-left: 0!important;}
.nopadding-right-lg {padding-right: 0!important;}

@media (max-width: 576px) {
    .nopadding-xs {
        padding-left: 0!important;
        padding-right: 0!important;
    }
    .nopadding-left-xs {padding-left: 0!important;}
    .nopadding-right-xs {padding-right: 0!important;}
}

@media (max-width: 768px) {
    .nopadding-sm {
        padding-left: 0!important;
        padding-right: 0!important;
    }
    .nopadding-left-sm {padding-left: 0!important;}
    .nopadding-right-sm {padding-right: 0!important;}
}
@media (max-width: 992px) {
    .nopadding-md {
        padding-left: 0!important;
        padding-right: 0!important;
    }
    .nopadding-left-md {padding-left: 0!important;}
    .nopadding-right-md {padding-right: 0!important;}
}

Reducing just the padding on the columns won't make the trick, as you will extend the width of the page, making it uneven with the rest of your page, say navbar. You need to equally reduce the negative margin on the row. Taking @martinedwards' LESS example:

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