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>

我已经为任意数量的列创建了基于bootstrap定义的SASS mixin定义(个人而言，除了12列，我使用8、10和24列):

// Extended bootstrap grid system
//
// Framework grid generation
//
// Based on Bootstrap 'bootstrap/_grid-framework.scss'. Generates classes in form of `.col-(size)-x-num` of width x/num.

@mixin make-extended-grid-columns($num-columns, $i: 1, $list: ".col-xs-#{$i}-#{$num-columns}, .col-sm-#{$i}-#{$num-columns}, .col-md-#{$i}-#{$num-columns}, .col-lg-#{$i}-#{$num-columns}") {
    @for $i from (1 + 1) through $num-columns {
        $list: "#{$list}, .col-xs-#{$i}-#{$num-columns}, .col-sm-#{$i}-#{$num-columns}, .col-md-#{$i}-#{$num-columns}, .col-lg-#{$i}-#{$num-columns}";
    }
    #{$list} {
        position: relative;
        min-height: 1px;
        padding-left:  ($grid-gutter-width / 2);
        padding-right: ($grid-gutter-width / 2);
    }
}


@mixin float-extended-grid-columns($class, $num-columns, $i: 1, $list: ".col-#{$class}-#{$i}-#{$num-columns}") {
    @for $i from (1 + 1) through $num-columns {
        $list: "#{$list}, .col-#{$class}-#{$i}-#{$num-columns}";
    }
    #{$list} {
        float: left;
    }
}


@mixin calc-extended-grid-column($index, $num-columns, $class, $type) {
    @if ($type == width) and ($index > 0) {
        .col-#{$class}-#{$index}-#{$num-columns} {
            width: percentage(($index / $num-columns));
        }
    }
    @if ($type == push) and ($index > 0) {
        .col-#{$class}-push-#{$index}-#{$num-columns} {
            left: percentage(($index / $num-columns));
        }
    }
    @if ($type == pull) and ($index > 0) {
        .col-#{$class}-pull-#{$index}-#{$num-columns} {
            right: percentage(($index / $num-columns));
        }
    }
    @if ($type == offset) and ($index > 0) {
        .col-#{$class}-offset-#{$index}-#{$num-columns} {
            margin-left: percentage(($index / $num-columns));
        }
    }
}

@mixin loop-extended-grid-columns($num-columns, $class, $type) {
    @for $i from 1 through $num-columns - 1 {
        @include calc-extended-grid-column($i, $num-columns, $class, $type);
    }
}

@mixin make-extended-grid($class, $num-columns) {
    @include float-extended-grid-columns($class, $num-columns);
    @include loop-extended-grid-columns($num-columns, $class, width);
    @include loop-extended-grid-columns($num-columns, $class, pull);
    @include loop-extended-grid-columns($num-columns, $class, push);
    @include loop-extended-grid-columns($num-columns, $class, offset);
}

你可以简单地创建类:

$possible-number-extended-grid-columns: 8, 10, 24;

@each $num-columns in $possible-number-extended-grid-columns {

  // Columns

  @include make-extended-grid-columns($num-columns);

  // Extra small grid

  @include make-extended-grid(xs, $num-columns);

  // Small grid

  @media (min-width: $screen-sm-min) {
    @include make-extended-grid(sm, $num-columns);
  }

  // Medium grid

  @media (min-width: $screen-md-min) {
    @include make-extended-grid(md, $num-columns);
  }

  // Large grid

  @media (min-width: $screen-lg-min) {
    @include make-extended-grid(lg, $num-columns);
  }

}

我希望有人会觉得它有用

最简单的方法是在行中添加row-cols-5。点击这里阅读更多

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

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/css/bootstrap.min.css" rel="stylesheet"> <div class="container"> <div class="row row-cols-5"> <div class="col border bg-primary">Col 1</div> <div class="col border bg-primary">Col 2</div> <div class="col border bg-primary">Col 3</div> <div class="col border bg-primary">Col 4</div> <div class="col border bg-primary">Col 5</div> <div class="col border bg-primary">Col 6</div> <div class="col border bg-primary">Col 7</div> </div> </div>

如何在引导中添加5列网格

.col-lg-1-5,.col-md-1-5,.col-sm-1-5,.col-xs-1-5{min-height:1px;padding-left:15px;padding-right:15px;position:relative; width:100%;box-sizing:border-box;} .item{width:100%;height:100px; background-color:#cfcfcf;} .col-xs-1-5{width: 20%;float:left;} } @media (min-width: 767px){ .col-sm-1-5{width: 20%;float:left;} } @media (min-width: 992px){ .col-md-1-5{width: 20%;float:left;} } @media (min-width: 1200px){ .col-lg-1-5{width: 20%;float:left;} } <div class="row"> <div class="col-sm-1-5"> <div class="item">Item 1</div> </div> <div class="col-sm-1-5"> <div class="item">Item 2</div> </div> <div class="col-sm-1-5"> <div class="item">Item 3</div> </div> <div class="col-sm-1-5"> <div class="item">Item 4</div> </div> <div class="col-sm-1-5"> <div class="item">Item 5</div> </div> </div>

这个很棒:http://www.ianmccullough.net/5-column-bootstrap-layout/

只做:

<div class="col-xs-2 col-xs-15">

和CSS:

.col-xs-15{
    width:20%;
}

Bootstrap默认可以缩放到12列?这意味着如果我们想要创建一个宽度相同的12列布局，我们将在div class="col-md-1"中写入12次。

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