用于引导4

Bootstrap 4现在默认使用flexbox，所以你可以直接使用它的神奇力量。查看自动布局列，根据嵌套的列的数量动态调整宽度。

这里有一个例子:

<div class="row">
   <div class="col">
      1 of 5
   </div>
   <div class="col">
      2 of 5
   </div>
   <div class="col">
      3 of 5
   </div>
   <div class="col">
      4 of 5
   </div>
   <div class="col">
      5 of 5
   </div>
</div>

演示工作

引导3

一个奇妙的全宽5列布局与Twitter引导创建在这里。

这是迄今为止最先进的解决方案，因为它与Bootstrap 3无缝地工作。它允许您一遍又一遍地重用这些类，并与当前的Bootstrap类一起用于响应式设计。

CSS: 将其添加到全局样式表中，甚至添加到bootstrap.css文档的底部。

.col-xs-5ths,
.col-sm-5ths,
.col-md-5ths,
.col-lg-5ths {
    position: relative;
    min-height: 1px;
    padding-right: 15px;
    padding-left: 15px;
}

.col-xs-5ths {
    width: 20%;
    float: left;
}

@media (min-width: 768px) {
    .col-sm-5ths {
        width: 20%;
        float: left;
    }
}

@media (min-width: 992px) {
    .col-md-5ths {
        width: 20%;
        float: left;
    }
}

@media (min-width: 1200px) {
    .col-lg-5ths {
        width: 20%;
        float: left;
    }
}

好好利用它!例如，如果你想创建一个div元素，它在中等屏幕上表现为五列布局，而在较小的屏幕上表现为两列布局，你只需要使用这样的东西:

<div class="row">
    <div class="col-md-5ths col-xs-6">
       ...
    </div>
</div>

工作演示-展开框架，看看列变得有响应。

另一个演示-将新的col-*-5ths类与其他类合并，如col-*-3和col-*-2。调整帧的大小，在响应视图中看到它们都改变为col-xs-6。

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。

保持原始的12列引导，不要自定义它。你唯一需要做的修改是一些css之后的原始引导响应css，像这样:

下面的代码已经为Bootstrap 2.3.2进行了测试:

<style type="text/css">
/* start of modification for 5 columns */
@media (min-width: 768px){
    .fivecolumns .span2 {
        width: 18.297872340425532%;
        *width: 18.2234042553191494%;
    }
}
@media (min-width: 1200px) {
    .fivecolumns .span2 {
        width: 17.9487179487179488%;
        *width: 17.87424986361156592%;
    }
}
@media (min-width: 768px) and (max-width: 979px) {
    .fivecolumns .span2 {
        width: 17.79005524861878448%;
        *width: 17.7155871635124022%;
    }
}
/* end of modification for 5 columns */
</style>

和html:

<div class="row-fluid fivecolumns">
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
</div>

注意:即使span2乘以5不等于12列，你明白了吧:)

可以在这里找到一个工作示例http://jsfiddle.net/v3Uy5/6/

对于twitter bootstrap 3，这是最简单的方法来实现这一点:

<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="width: 20%;">
<section class="col col-sm-3" style="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

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>
