一个解决方案，不需要大量的CSS，也不调整bootstrap默认12col布局:

http://jsfiddle.net/0ufdyeur/1/

HTML:

<div class="stretch">
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
</div>

CSS:

@media (min-width: 1200px) { /*if not lg, change this criteria*/
  .stretch{
    width: 120%; /*the actual trick*/
  }
}

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。

.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);

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%;
}

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);
    }
}
