title: Bootstrap 4 popover arrow outline
body: <p>I have found 100 different answers to this question but none seem to work. I am trying to get rid of the outline on the Bootstrap 4 popover arrow. I have tried every pseudo target I can think of. I am using a bottom popover. Any help is super appreciated.</p>
