为5列布局创建自定义引导下载

进入Bootstrap 2.3.2(或Bootstrap 3)自定义页面，设置以下变量(不要输入分号):

@gridColumns:           5;
@gridColumnWidth:       172px;
@gridColumnWidth1200:   210px;
@gridColumnWidth768:    128px;
@gridGutterWidth768:    21px;

下载您的构建。这个网格将适合默认的容器，(几乎)保留默认的沟槽宽度。

注意:如果你使用LESS，更新变量。而不是更少。

最好的方法

只在行中添加.row-cols-5类。每一行有5个div。

<div class="container-fluid">
    <div class="row row-cols-5">
        <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 class="col">6</div>
        <div class="col">7</div>
        <div class="col">8</div>
        <div class="col">9</div>
        <div class="col">10</div>
    </div>
</div>

使用响应式.row-cols-*类快速设置最能呈现内容和布局的列数。普通的.col-*类应用于单个列(例如，.col-md-4)，而行列类在父.row上设置为快捷方式。

row-cols - * row-cols-sm - * row-cols-md - * row-cols-lg - * row-cols-xl - *

你也可以使用附带的Sass mixin, row-cols():

.element {
  // Three columns to start
  @include row-cols(3);

  // Five columns from medium breakpoint up
  @include media-breakpoint-up(md) {
    @include row-cols(5);
  }
}

在bootstrap v4.3.1中，它是一个12 / 5 = 2.4列宽的列。我们称它为col-2dot4(以及col-sm-2dot4, col-md-2dot4，…)

每一列应该有20%的可用空间。

SCSS代码如下所示:

@mixin make-5-grid-column($columns: $grid-columns, $gutter: $grid-gutter-width, $breakpoints: $grid-breakpoints) {

  // Common properties for all breakpoints
  %grid-column {
    position: relative;
    width: 100%;
    padding-right: $gutter / 2;
    padding-left: $gutter / 2;
  }

  @each $breakpoint in map-keys($breakpoints) {
    $infix: breakpoint-infix($breakpoint, $breakpoints);

    .col#{$infix}-2dot4 {
      @extend %grid-column;
    }

    .col#{$infix},
    .col#{$infix}-auto {
      @extend %grid-column;
    }

    @include media-breakpoint-up($breakpoint, $breakpoints) {

      // Provide basic `.col-{bp}` classes for equal-width flexbox columns
      .col#{$infix} {
        flex-basis: 0;
        flex-grow: 1;
        max-width: 100%;
      }

      .col#{$infix}-auto {
        flex: 0 0 auto;
        width: auto;
        max-width: 100%; // Reset earlier grid tiers
      }


      .col#{$infix}-2dot4 {
        @include make-col(1, 5);
      }
    }
  }
}

@if $enable-grid-classes {
  @include make-5-grid-column();
}

.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%; } }

使用5个div，类为span2，并给第一个类为offset1。

<div class="row-fluid">
    <div class="span2 offset1"></div>
    <div class="span2"></div>
    <div class="span2"></div>
    <div class="span2"></div>
    <div class="span2"></div>
</div>

瞧! 五列等距居中。

在引导3.0中，这段代码看起来像

<div class="row">
    <div class="col-md-2 col-md-offset-1"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
    <div class="col-md-2"></div>
</div>

更新

因为bootstrap 4.0默认使用Flexbox:

<div class="row">
    <div class="col"></div>
    <div class="col"></div>
    <div class="col"></div>
    <div class="col"></div>
    <div class="col"></div>
</div>
