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。

.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%; } }

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>

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>

Bootstrap或其他网格系统并不总是意味着更简单和更好。 在你的.container或.row(保持你的响应式布局)中，你可以创建5个div(使用类.col f.e.)，并像这样添加css: .col { 宽度:20%; 浮:左 };

更新:现在最好使用flexbox

<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%;
}
