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>

.col-xs-2-4 { position: relative; float: left; width: 20%; min-height: 1px; padding-left: 15px; padding-right: 15px; } .col-sm-2-4 { position: relative; min-height: 1px; padding-left: 15px; padding-right: 15px; } @media (min-width: 768px) { .col-sm-2-4 { float: left; width: 20%; } } .col-md-2-4 { position: relative; min-height: 1px; padding-left: 15px; padding-right: 15px; } @media (min-width: 992px) { .col-md-2-4 { float: left; width: 20%; } } .col-lg-2-4 { position: relative; min-height: 1px; padding-left: 15px; padding-right: 15px; } @media (min-width: 1200px) { .col-lg-2-4 { float: left; width: 20%; } }

我对Mafnah的答案进行了投票，但再看一遍，如果你保持默认的边际，我建议下面的答案更好。

<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 {
    width: 17.9%;
}

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();
}

在Bootstrap 3中启用5列的另一种方法是修改Bootstrap默认使用的12列格式。然后创建一个20列的网格(在Bootstrap网站上使用自定义或使用LESS/SASS版本)。

要在引导网站上进行自定义，请访问自定义和下载页面，将变量@grid-columns从12更新为20。然后，您将能够创建4以及5列。

它可以通过嵌套和使用一点css覆盖来完成。

<div class="col-sm-12">
<div class="row">
  <div class="col-sm-7 five-three">
    <div class="row">
      <div class="col-sm-4">
      Column 1
      </div>
      <div class="col-sm-4">
      Column 2
      </div>
      <div class="col-sm-4">
      Column 3
      </div><!-- end inner row -->
    </div>
  </div>
  <div class="col-sm-5 five-two">
    <div class="row">
      <div class="col-sm-6">
        Col 4
      </div>
      <div class="col-sm-6">
      Col 5
      </div>
    </div><!-- end inner row -->
  </div>
</div>​<!-- end outer row -->

然后是css

@media  (min-width: 768px) {
div.col-sm-7.five-three {
width: 60% !important;
}

div.col-sm-5.five-two {
width: 40% !important;
}

}

下面是一个例子:5等列的例子
