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

最简单的方法是在行中添加row-cols-5。点击这里阅读更多

<div class="container">
  <div class="row row-cols-5">
    <div class="col">Col 1</div>
    <div class="col">Col 2</div>
    <div class="col">Col 3</div>
    <div class="col">Col 4</div>
    <div class="col">Col 5</div>
  </div>
</div>

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/css/bootstrap.min.css" rel="stylesheet"> <div class="container"> <div class="row row-cols-5"> <div class="col border bg-primary">Col 1</div> <div class="col border bg-primary">Col 2</div> <div class="col border bg-primary">Col 3</div> <div class="col border bg-primary">Col 4</div> <div class="col border bg-primary">Col 5</div> <div class="col border bg-primary">Col 6</div> <div class="col border bg-primary">Col 7</div> </div> </div>

五列显然不是bootstrap设计的一部分。

但是对于Bootstrap v4 (alpha)，有两件事可以帮助处理复杂的网格布局

Flex (http://v4-alpha.getbootstrap.com/getting-started/flexbox/)，新的元素类型(官方- https://www.w3.org/TR/css-flexbox-1/) 响应式实用程序(http://v4-alpha.getbootstrap.com/layout/responsive-utilities/)

简单来说，我在用

<style>
.flexc { display: flex; align-items: center; padding: 0; justify-content: center; }
.flexc a { display: block; flex: auto; text-align: center; flex-basis: 0; }
</style>
<div class="container flexc hidden-sm-down">
  <!-- content to show in MD and larger viewport -->
  <a href="#">Link/Col 1</a>
  <a href="#">Link/Col 2</a>
  <a href="#">Link/Col 3</a>
  <a href="#">Link/Col 4</a>
  <a href="#">Link/Col 5</a>
</div>
<div class="container hidden-md-up">
  <!-- content to show in SM and smaller viewport, I don't think 5 cols in smaller viewport are gonna be alright :) -->
</div>

不管是5 7 9 11 13还是其他概率，都没问题。 我非常确定12网格标准能够服务于90%以上的用例——所以让我们以这种方式设计——也更容易开发!

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:)

可以在这里找到一个工作示例http://jsfiddle.net/v3Uy5/6/

对于Bootstrap 3，如果你想要全宽，并且正在使用LESS、SASS或类似的东西，你所要做的就是使用Bootstrap的mixin函数make-md-column、make-sm-column等。

少:

.col-lg-2-4{
  .make-lg-column(2.4)
}
.col-md-2-4{
  .make-md-column(2.4)
}
.col-sm-2-4{
  .make-sm-column(2.4)
}

萨斯:

.col-lg-2-4{
  @include make-lg-column(2.4)
}
.col-md-2-4{
  @include make-md-column(2.4)
}
.col-sm-2-4{
  @include make-sm-column(2.4)
}

你不仅可以使用这些mixin构建真正的全宽度引导列类，还可以构建所有相关的辅助类，如.col-md-push-*， .col-md-pull-*和.col-md-offset-*:

少:

.col-md-push-2-4{
  .make-md-column-push(2.4)
}
.col-md-pull-2-4{
  .make-md-column-pull(2.4)
}
.col-md-offset-2-4{
  .make-md-column-offset(2.4)
}

萨斯:

.col-md-push-2-4{
  @include make-md-column-push(2.4)
}
.col-md-pull-2-4{
  @include make-md-column-pull(2.4)
}
.col-md-offset-2-4{
  @include make-md-column-offset(2.4)
}

其他答案谈到设置@gridColumns，这是完全有效的，但这改变了所有引导的核心列宽度。使用上述mixin函数将在默认的引导列之上添加5列布局，因此它不会破坏任何第三方工具或现有样式。

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;
    }
}
