title: Sizing Bootstrap Alerts
body: <p>What is the best way to change the size of Bootstrap 4 alerts to match input sizes?</p>
  
  <p>I am using <code>col-form-label-sm</code>, <code>form-control-sm</code>  and <code>btn-sm</code> for form elements but there is no equivalent <code>alert-sm</code> for the Alert component.</p>
  
  <p>I've tried adding the utility <code>small</code> class to the alert div but this results in a smaller font-size than the other elements and the close button is not in the middle anymore.</p>
