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);
    }
}

/***************************************/
/* Using default bootstrap now
/***************************************/

@import  (multiple) "../bootstrap-3.2.0/less/variables.less";
@import  (multiple) "../bootstrap-3.2.0/less/mixins.less";

/* ... your normal less definitions */

如何在引导中添加5列网格

.col-lg-1-5,.col-md-1-5,.col-sm-1-5,.col-xs-1-5{min-height:1px;padding-left:15px;padding-right:15px;position:relative; width:100%;box-sizing:border-box;} .item{width:100%;height:100px; background-color:#cfcfcf;} .col-xs-1-5{width: 20%;float:left;} } @media (min-width: 767px){ .col-sm-1-5{width: 20%;float:left;} } @media (min-width: 992px){ .col-md-1-5{width: 20%;float:left;} } @media (min-width: 1200px){ .col-lg-1-5{width: 20%;float:left;} } <div class="row"> <div class="col-sm-1-5"> <div class="item">Item 1</div> </div> <div class="col-sm-1-5"> <div class="item">Item 2</div> </div> <div class="col-sm-1-5"> <div class="item">Item 3</div> </div> <div class="col-sm-1-5"> <div class="item">Item 4</div> </div> <div class="col-sm-1-5"> <div class="item">Item 5</div> </div> </div>

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*/
  }
}

<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: 20%;
}

五列显然不是bootstrap设计的一部分。

但是对于Bootstrap v4 (alpha)，有两件事可以帮助处理复杂的网格布局

Flex (http://v4-alpha.getbootstrap.com/getting-started/flexbox/)，新的元素类型(官方- https://www.w3.org/TR/css-flexbox-1/) 响应式实用程序(http://v4-alpha.getbootstrap.com/layout/responsive-utilities/)

简单来说，我在用

<style>
.flexc { display: flex; align-items: center; padding: 0; justify-content: center; }
.flexc a { display: block; flex: auto; text-align: center; flex-basis: 0; }
</style>
<div class="container flexc hidden-sm-down">
  <!-- content to show in MD and larger viewport -->
  <a href="#">Link/Col 1</a>
  <a href="#">Link/Col 2</a>
  <a href="#">Link/Col 3</a>
  <a href="#">Link/Col 4</a>
  <a href="#">Link/Col 5</a>
</div>
<div class="container hidden-md-up">
  <!-- content to show in SM and smaller viewport, I don't think 5 cols in smaller viewport are gonna be alright :) -->
</div>

不管是5 7 9 11 13还是其他概率，都没问题。 我非常确定12网格标准能够服务于90%以上的用例——所以让我们以这种方式设计——也更容易开发!
