不需要编辑CSS的最简单的解决方案是:

<div class="row">
  <div class="btn-group btn-group-justified">
    <div class="btn-group">
      <div class="col-sm-12">Column 1</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 2</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 3</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 4</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 5</div>
    </div>
  </div>
</div>

如果你需要这些打破任何断点，只要使btn-group块。希望这能帮助到一些人。

有人使用bootstrap-sass (v3)，下面是使用bootstrap混合的5列的简单代码:

  .col-xs-5ths {
     @include make-xs-column(2.4);
  }

  @media (min-width: $screen-sm-min) {
     .col-sm-5ths {
        @include make-sm-column(2.4);
     }
  }

  @media (min-width: $screen-md-min) {
     .col-md-5ths {
        @include make-md-column(2.4);
     }
  }

  @media (min-width: $screen-lg-min) {
     .col-lg-5ths {
        @include make-lg-column(2.4);
     }
  }

确保你已经包括:

@import "bootstrap/variables";
@import "bootstrap/mixins";

5列布局与Twitter引导风格

.col-xs-15 {
    position: relative;
    min-height: 1px;
    padding-right: 10px;
    padding-left: 10px;
}

.col-xs-15 {
    width: 100%;
    float: left;
}
@media (min-width: 768px) {
.col-xs-15 {
        width: 50%;
        float: left;
    }
}
@media (min-width: 992px) {
    .col-xs-15 {
        width: 20%;
        float: left;
    }
}
@media (min-width: 1200px) {
    .col-xs-15 {
        width: 20%;
        float: left;
    }
}

var cols = $(".container .item").length;
if (cols == 5){
    $('div.item').removeClass('col-md-2..etc').addClass('col-md-3').css('width', '20%');
 }

Jquery和完成!框架!

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:)

不需要编辑CSS的最简单的解决方案是:

<div class="row">
  <div class="btn-group btn-group-justified">
    <div class="btn-group">
      <div class="col-sm-12">Column 1</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 2</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 3</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 4</div>
    </div>
    <div class="btn-group">
      <div class="col-sm-12">Column 5</div>
    </div>
  </div>
</div>

如果你需要这些打破任何断点，只要使btn-group块。希望这能帮助到一些人。
