引导4

我看了所有的答案，没有找到“显而易见的答案”。基本上，您需要做的是选取任何自举列(例如col-2)并编辑一些值。在这个例子中，我使用的是.col-custom类。

5个相等的列表示每个列占用20%，因此:flex:0 0 20%和max-width:20%。同样的方法，你可以创建其他数量的列(7,9,11,84或任何你想要的)。

您可以创建自定义宽度的CSS变量，并在项目中使用它。就像这样:

:root {
  --col-custom: 20%;
}

.col-custom {
  flex: 0 0 var(--col-custom);
  max-width: var(--col-custom);
}

工作的例子:

.col-custom, .col-sm-custom, .col-md-custom, .col-lg-custom, .col-xl-custom { position: relative; width: 100%; padding-right: 15px; padding-left: 15px; } .col-custom { flex: 0 0 20%; max-width: 20%; } @media (min-width: 576px){ .col-sm-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 768px){ .col-md-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 992px){ .col-lg-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 1200px){ .col-xl-custom { flex: 0 0 20%; max-width: 20%; } } /*DEMO*/ .col-custom,.col-sm-custom,.col-md-custom,.col-lg-custom,.col-xl-custom{height:100px;border:1px red solid} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"> <div class="container-fluid"> <div class="row"> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> </div> </div>

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>

下面是@machineaddict和@Mafnah回答的组合，为Bootstrap 3重写(到目前为止对我来说很好):

@media (min-width: 768px){
    .fivecolumns .col-md-2, .fivecolumns .col-sm-2, .fivecolumns .col-lg-2  {
        width: 20%;
        *width: 20%;
    }
}
@media (min-width: 1200px) {
    .fivecolumns .col-md-2, .fivecolumns .col-sm-2, .fivecolumns .col-lg-2 {
        width: 20%;
        *width: 20%;
    }
}
@media (min-width: 768px) and (max-width: 979px) {
    .fivecolumns .col-md-2, .fivecolumns .col-sm-2, .fivecolumns .col-lg-2 {
        width: 20%;
        *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

<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%;
}
