在bootstrap v4.3.1中，它是一个12 / 5 = 2.4列宽的列。我们称它为col-2dot4(以及col-sm-2dot4, col-md-2dot4，…)

每一列应该有20%的可用空间。

SCSS代码如下所示:

@mixin make-5-grid-column($columns: $grid-columns, $gutter: $grid-gutter-width, $breakpoints: $grid-breakpoints) {

  // Common properties for all breakpoints
  %grid-column {
    position: relative;
    width: 100%;
    padding-right: $gutter / 2;
    padding-left: $gutter / 2;
  }

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

    .col#{$infix}-2dot4 {
      @extend %grid-column;
    }

    .col#{$infix},
    .col#{$infix}-auto {
      @extend %grid-column;
    }

    @include media-breakpoint-up($breakpoint, $breakpoints) {

      // Provide basic `.col-{bp}` classes for equal-width flexbox columns
      .col#{$infix} {
        flex-basis: 0;
        flex-grow: 1;
        max-width: 100%;
      }

      .col#{$infix}-auto {
        flex: 0 0 auto;
        width: auto;
        max-width: 100%; // Reset earlier grid tiers
      }


      .col#{$infix}-2dot4 {
        @include make-col(1, 5);
      }
    }
  }
}

@if $enable-grid-classes {
  @include make-5-grid-column();
}

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

附注:这将不是全宽度的(它将从屏幕的左右略微缩进)

代码应该看起来像这样

<div class="col-sm-2 col-sm-offset-1"></div>
<div class="col-sm-2"></div>
<div class="col-sm-2"></div>
<div class="col-sm-2"></div>
<div class="col-sm-2"></div>

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

引导4，每行可变列数

如果你想每行最多有5列，这样每一行的列数仍然只占一行的1/5，解决方案是使用Bootstrap 4的mixins:

SCSS:

.col-2-4 {
    @include make-col-ready(); // apply standard column margins, padding, etc.
    @include make-col(2.4); // 12/5 = 2.4
}
.col-sm-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(sm) {
        @include make-col(2.4);
    }
}
.col-md-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(md) {
        @include make-col(2.4);
    }
}
.col-lg-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(lg) {
        @include make-col(2.4);
    }
}
.col-xl-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(xl) {
        @include make-col(2.4);
    }
}

HTML:

<div class="container">    
  <div class="row">
    <div class="col-12 col-sm-2-4">1 of 5</div>
    <div class="col-12 col-sm-2-4">2 of 5</div>
    <div class="col-12 col-sm-2-4">3 of 5</div>
    <div class="col-12 col-sm-2-4">4 of 5</div>
    <div class="col-12 col-sm-2-4">5 of 5</div>
  </div>
  <div class="row">
    <div class="col-12 col-sm-2-4">1 of 2</div> <!-- same width as column "1 of 5" above -->
    <div class="col-12 col-sm-2-4">2 of 2</div> <!-- same width as column "2 of 5" above -->
  </div>
</div>

为5列布局创建自定义引导下载

进入Bootstrap 2.3.2(或Bootstrap 3)自定义页面，设置以下变量(不要输入分号):

@gridColumns:           5;
@gridColumnWidth:       172px;
@gridColumnWidth1200:   210px;
@gridColumnWidth768:    128px;
@gridGutterWidth768:    21px;

下载您的构建。这个网格将适合默认的容器，(几乎)保留默认的沟槽宽度。

注意:如果你使用LESS，更新变量。而不是更少。

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%;
}
