Bootstrap columns stacking vertically on mobile device

Question

I have a simple bootstrap grid layout. I do not want the columns to stack vertically even on small devices.

<div class="container">
<div class="row">
  <div class="col-sm-4 col-xs-4 col-md-4">1</div>
  <div class="col-sm-4 col-xs-4 col-md-4">2</div>
  <div class="col-sm-4 col-xs-4 col-md-4">3</div>
</div>

Answer 1

The columns are stacking vertically because you're using Bootstrap 4, and the -xs- infix is no longer used. Just use col-4..

  <div class="container border-show center-div">
    <div class="row">
      <div class="col-4 border-show">1</div>
      <div class="col-4 border-show">2</div>
      <div class="col-4 border-show">3</div>
    </div>
  </div>
