如果使用bootstrap 4和SASS (+ bootstrap变量)，您可以使用以下简化的答案:

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

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

  @include media-breakpoint-up($breakpoint, $grid-breakpoints) {
    .col#{$infix}-fifth {
      flex: 0 0 20%;
      max-width: 20%;
    }
  }
}

还支持断点，您可以简单地添加新的.col#{$infix}-xxx类

用于引导5或更高版本

可以使用row-cols- class名称。

例如:row-col -1, row-col -5, row-col -lg-5

<div class="container">
  <div class="row row-cols-5">
     // place your all cols here
  </div>
</div>

更多信息请阅读官方文档

.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%; } }

在bootstrap 3中，我认为我们可以这样做，删除左右边距:

<div class="row this_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>

和CSS

.this_row {
    margin: 0 -5%;
}

Boostrap今天提供了用内置类均匀填充一行的可能性，这些内置类不告诉十二列中有多少列要跨度:

你可以使用col/col-xx:

div div div { border: solid; margin: 2px;/* this can be added without breaking the row */ } div div div:before { content:attr(class);/* show class used */ color:crimson <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" /> <p>Class used , play snippet in full page to test behavior on resizing :</p> <div class="container"> <div class="row"> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> <div class="col-sm"></div> </div> <div class="row"> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> <div class="col-md"></div> </div> <div class="row"> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> </div> </div>

Flex-grow-x也可以使用

div div div { border: solid; /* it allows margins too */ margin: 3px; } div div div:before { content: attr(class); /* show class used */ color: crimson } <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" /> <div class="container"> <div class="row"> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> <div class="flex-grow-1"></div> </div> </div>

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";
