创建5个类为col-sm-2的元素，并在第一个元素中添加类为col-sm-offset-1

<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 { 宽度:17.9%; ｝

附注:这将不是全宽度(它将从屏幕的左右稍微缩进)。

代码应该看起来像这样。

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>

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>

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;
    }
}

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();
}

创建5个类为col-sm-2的元素，并在第一个元素中添加类为col-sm-offset-1

附注:这将不是全宽度的(它将从屏幕的左右略微缩进)

代码应该看起来像这样

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