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。

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%;
}

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>

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。

保持原始的12列引导，不要自定义它。你唯一需要做的修改是一些css之后的原始引导响应css，像这样:

下面的代码已经为Bootstrap 2.3.2进行了测试:

<style type="text/css">
/* start of modification for 5 columns */
@media (min-width: 768px){
    .fivecolumns .span2 {
        width: 18.297872340425532%;
        *width: 18.2234042553191494%;
    }
}
@media (min-width: 1200px) {
    .fivecolumns .span2 {
        width: 17.9487179487179488%;
        *width: 17.87424986361156592%;
    }
}
@media (min-width: 768px) and (max-width: 979px) {
    .fivecolumns .span2 {
        width: 17.79005524861878448%;
        *width: 17.7155871635124022%;
    }
}
/* end of modification for 5 columns */
</style>

和html:

<div class="row-fluid fivecolumns">
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
</div>

注意:即使span2乘以5不等于12列，你明白了吧:)
