Bootstrap - 5 column layout

5 Columns with Bootstrap 4

Here is 5 equal, full-width columns (no extra CSS or SASS) using the auto-layout grid..

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

This solution works because Bootstrap 4 is now flexbox. You can get the 5 colums to wrap within the same .row using a clearfix break such as <div class="col-12"></div> or <div class="w-100"></div> every 5 columns.

Update 2020

As of Bootstrap 4.4, you can also use the row-cols-5 class on the row...

<div class="container">
    <div class="row row-cols-5">
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
    </div>
</div>

Default bootstrap(version 4.6) grid allows you to do this.
You can make 7, 7 11 columns in a row.

<div class="container">
  <div class="row row-cols-5">
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
  </div>
</div>

Responsive version of this.

<div class="container">
  <div class="row row-cols-2 row-cols-sm-3 row-cols-md-4 row-cols-lg-5 row-cols-xl-5">
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
    <div class="col">Column</div>
  </div>
</div>

UPDATE, 2021: for modern Bootstrap (4+), I recommend Zim's answer due to it's natural way of using Bootstrap flex classes

.col-xs-2{
    background:#00f;
    color:#FFF;
}
.col-half-offset{
    margin-left:4.166666667%
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
    <div class="row" style="border: 1px solid red">
        <div class="col-xs-2" id="p1">One</div>
        <div class="col-xs-2 col-half-offset" id="p2">Two</div>
        <div class="col-xs-2 col-half-offset" id="p3">Three</div>
        <div class="col-xs-2 col-half-offset" id="p4">Four</div>
        <div class="col-xs-2 col-half-offset" id="p5">Five</div>
        <div>lorem</div>
    </div>
</div>

This should be ok.
