在我看来，像这样使用Less语法更好。 这个答案是基于@fizzix的回答

这样列使用用户可能覆盖的变量(@grid-gutter-width, media breakpoints)， 5列的行为与12列网格的行为匹配。

/*
 * Special grid for ten columns, 
 * using its own scope 
 * so it does not interfere with the rest of the code
 */

& {
    @import (multiple) "../bootstrap-3.2.0/less/variables.less";
    @grid-columns: 5;
    @import  (multiple) "../bootstrap-3.2.0/less/mixins.less";

    @column: 1;
    .col-xs-5ths {
        .make-xs-column(@column);
    }

    .col-sm-5ths {
        .make-sm-column(@column);
    }

    .col-md-5ths {
        .make-md-column(@column);
    }

    .col-lg-5ths {
        .make-lg-column(@column);
    }
}

<div class="equal row-fluid">

    <div class="span2"></div>
    <div class="span2"></div>
</div>

.equal .span2 {
    width: 20%;
}

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

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>

引导4

我看了所有的答案，没有找到“显而易见的答案”。基本上，您需要做的是选取任何自举列(例如col-2)并编辑一些值。在这个例子中，我使用的是.col-custom类。

5个相等的列表示每个列占用20%，因此:flex:0 0 20%和max-width:20%。同样的方法，你可以创建其他数量的列(7,9,11,84或任何你想要的)。

您可以创建自定义宽度的CSS变量，并在项目中使用它。就像这样:

:root {
  --col-custom: 20%;
}

.col-custom {
  flex: 0 0 var(--col-custom);
  max-width: var(--col-custom);
}

工作的例子:

.col-custom, .col-sm-custom, .col-md-custom, .col-lg-custom, .col-xl-custom { position: relative; width: 100%; padding-right: 15px; padding-left: 15px; } .col-custom { flex: 0 0 20%; max-width: 20%; } @media (min-width: 576px){ .col-sm-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 768px){ .col-md-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 992px){ .col-lg-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 1200px){ .col-xl-custom { flex: 0 0 20%; max-width: 20%; } } /*DEMO*/ .col-custom,.col-sm-custom,.col-md-custom,.col-lg-custom,.col-xl-custom{height:100px;border:1px red solid} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"> <div class="container-fluid"> <div class="row"> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> </div> </div>

创建5个类为col-sm-2的元素，并在第一个元素中添加类为col-sm-offset-1

<div class="equal - row-fluid"> < div class = " span2 " > < / div > < div class = " span2 " > < / div > < div class = " span2 " > < / div > < div class = " span2 " > < / div > < div class = " span2 " > < / div > < / div > .equal .span2 { 宽度:17.9%; ｝

附注:这将不是全宽度(它将从屏幕的左右稍微缩进)。

代码应该看起来像这样。
