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";

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%;
}

引导4，每行可变列数

如果你想每行最多有5列，这样每一行的列数仍然只占一行的1/5，解决方案是使用Bootstrap 4的mixins:

SCSS:

.col-2-4 {
    @include make-col-ready(); // apply standard column margins, padding, etc.
    @include make-col(2.4); // 12/5 = 2.4
}
.col-sm-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(sm) {
        @include make-col(2.4);
    }
}
.col-md-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(md) {
        @include make-col(2.4);
    }
}
.col-lg-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(lg) {
        @include make-col(2.4);
    }
}
.col-xl-2-4 {
    @include make-col-ready();
    @include media-breakpoint-up(xl) {
        @include make-col(2.4);
    }
}

HTML:

<div class="container">    
  <div class="row">
    <div class="col-12 col-sm-2-4">1 of 5</div>
    <div class="col-12 col-sm-2-4">2 of 5</div>
    <div class="col-12 col-sm-2-4">3 of 5</div>
    <div class="col-12 col-sm-2-4">4 of 5</div>
    <div class="col-12 col-sm-2-4">5 of 5</div>
  </div>
  <div class="row">
    <div class="col-12 col-sm-2-4">1 of 2</div> <!-- same width as column "1 of 5" above -->
    <div class="col-12 col-sm-2-4">2 of 2</div> <!-- same width as column "2 of 5" above -->
  </div>
</div>

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%;">

更新2019

引导4.1 +

下面是5个相同的全宽列(没有额外的CSS或SASS)，使用自动布局网格:

<div class="container-fluid">
    <div class="row">
        <div class="col">1</div>
        <div class="col">2</div>
        <div class="col">3</div>
        <div class="col">4</div>
        <div class="col">5</div>
    </div>
</div>

这个解决方案是有效的，因为Bootstrap 4现在是flexbox。你可以让5列在相同的.row中使用换行符，如<div class="col-12"></div>或<div class="w-100"></div>每5列。

最简单的方法是在行中添加row-cols-5。点击这里阅读更多

<div class="container">
  <div class="row row-cols-5">
    <div class="col">Col 1</div>
    <div class="col">Col 2</div>
    <div class="col">Col 3</div>
    <div class="col">Col 4</div>
    <div class="col">Col 5</div>
  </div>
</div>
