I am attempting to create a responsive block in the center of my webpage with the help of Bootstrap. However, I am having trouble getting the columns to respond correctly to my bootstrap setup. Can anyone point out what I might be doing wrong?
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<div class="container">
<div class="row">
<div class="col-sm-12 col-md-10 mx-auto" style="background-color: blue; color: white;">
test column
</div>
