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

在bootstrap 3中有5个相等的列

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-half-offset{
    margin-left:4.166666667% !important;
    float: left;
}

<div className="row1 marginTop20">
    <div className="col-xs-12 col-sm-2 col-md-2">
        1
    </div>
    <div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
        2
    </div>
    <div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
        3
    </div>
    <div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
        4
    </div>
    <div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
        5
    </div>
    <div className="clearfix"></div>
</div>

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>

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);

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%;
}
