I have the following bootstrap-4 column structure:
<div class="container">
<div class="row">
<div class="col-xs-12 col-sm-4">A</div>
<div class="col-xs-6 col-sm-4">B</div>
<div class="col-xs-6 col-sm-4">C</div>
</div>
</div>
The expected column layout according to screen size is:
XS:
[ A ]
[B][C]
SM and up:
[A][B][C]
However, at XS each div takes the full width like this:
[A]
[B]
[C]
Check JSFiddle snippet here.
What could be wrong here?
