在bootstrap 3中，我认为我们可以这样做，删除左右边距:

<div class="row this_row">
    <div class="col-md-2 col-md-offset-1"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
</div>

和CSS

.this_row {
    margin: 0 -5%;
}

您可以使用小技巧，使colo -md-2与偏移解决方案全宽。它使用bootstrap删除(隐藏)15px填充的方法。

我的意思是添加“-”页边距。实际上是calc(-10% - 15px);两边都有空白。(10%为偏移宽度，15px为填充)。

唯一的缺点是它会使页面水平滚动，所以你需要在父行中隐藏overflow-x:。

css:
.row-xs-5 {
    margin-left: calc(-10% - 15px);
    margin-right: calc(-10% - 15px);
}
@media (min-width: 768px) {
  .row-sm-5 {
    margin-left: calc(-10% - 15px);
    margin-right: calc(-10% - 15px);
  }
}
@media (min-width: 992px) {
  .row-md-5 {
    margin-left: calc(-10% - 15px);
    margin-right: calc(-10% - 15px);
  }
}
@media (min-width: 1200px) {
  .row-lg-5 {
    margin-left: calc(-10% - 15px);
    margin-right: calc(-10% - 15px);
  }
}

html:
<div style="overflow-x:hidden;">
  <div class="row row-md-5">
    <div class="col-xs-6 col-md-2 col-md-offset-1">col1</div>
    <div class="col-xs-6 col-md-2">col2</div>
    <div class="col-xs-6 col-md-2">col3</div>
    <div class="col-xs-6 col-md-2">col4</div>
    <div class="col-xs-6 col-md-2 text-right">col5</div>
  </div>
</div>

更新2019

引导4.1 +

下面是5个相同的全宽列(没有额外的CSS或SASS)，使用自动布局网格:

<div class="container-fluid">
    <div class="row">
        <div class="col">1</div>
        <div class="col">2</div>
        <div class="col">3</div>
        <div class="col">4</div>
        <div class="col">5</div>
    </div>
</div>

这个解决方案是有效的，因为Bootstrap 4现在是flexbox。你可以让5列在相同的.row中使用换行符，如<div class="col-12"></div>或<div class="w-100"></div>每5列。

也请参阅:引导- 5列布局

Boostrap今天提供了用内置类均匀填充一行的可能性，这些内置类不告诉十二列中有多少列要跨度:

你可以使用col/col-xx:

div div div { border: solid; margin: 2px;/* this can be added without breaking the row */ } div div div:before { content:attr(class);/* show class used */ color:crimson <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" /> <p>Class used , play snippet in full page to test behavior on resizing :</p> <div class="container"> <div class="row"> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> </div> <div class="row"> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> </div> <div class="row"> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> </div> </div>

Flex-grow-x也可以使用

div div div { border: solid; /* it allows margins too */ margin: 3px; } div div div:before { content: attr(class); /* show class used */ color: crimson } <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" /> <div class="container"> <div class="row"> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> </div> </div>

我对这个问题的首选方法是基于make-grid-columns mixin，利用现有的Bootstrap变量创建一个SASS mixin。

// Custom Grid Columns
// 
// $name - determines the class names: eg. ".col-5ths, .col-sm-5ths ..."
// $size - determines the width (2.4 is one fifth of 12, the default number of columns)
@mixin custom-grid-columns($name, $size, $grid-columns: $grid-columns, $breakpoints: $grid-breakpoints) {
    $columns: round($grid-columns / $size);

    %custom-grid-column {
        @include make-col-ready();
    }

    @each $breakpoint in map-keys($breakpoints) {
        $infix: breakpoint-infix($breakpoint, $breakpoints);

        .col#{$infix}-#{$name} {
            @extend %custom-grid-column;
        }

        @include media-breakpoint-up($breakpoint, $breakpoints) {
            // Create column
            .col#{$infix}-#{$name} {
                @include make-col($size);
            }

            // Create offset
            @if not ($infix=="") {
                .offset#{$infix}-#{$name} {
                    @include make-col-offset($size);
                }
            }
        }
    }
}

然后可以调用mixin来生成自定义列类和偏移量类。

@include custom-grid-columns('5ths', 2.4);

对于twitter bootstrap 3，这是最简单的方法来实现这一点:

<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
