Css Bootstrap 4 - how to have vertical tabs on wider screens and horizontal on smaller -

i trying make tabs vertical on wider screens , horizontal on smaller screens, not sure how can achieve that. have tried adding flex-md-column , flex-lg-column nav tabs:

<ul class="nav nav-tabs flex-md-column flex-lg-column" id="mytab" role="tablist">   <li class="nav-item">     <a class="nav-link active" id="info-tab" data-toggle="tab" href="#info" role="tab" aria-controls="info" aria-expanded="true"><i class="ion-compose"></i> info</a>   </li>   <li class="nav-item">     <a class="nav-link" id="stats-tab" data-toggle="tab" href="#stats" role="tab" aria-controls="stats"><i class="ion-arrow-graph-up-right"></i> statistics</a>   </li>   <li class="nav-item">     <a class="nav-link" id="contact-tab" data-toggle="tab" href="#contact" role="tab" aria-controls="contact"><i class="ion-email"></i> contact</a>   </li> </ul> 

but, tabs take full width, , tabs content pushed below. how can fix that, tabs take width need, , content can go top, on side of nav-tabs?? have tried setting fixed width nav-items, but, didn't work.

all need combine appropriate flex classes , add little padding here , there. ;)

make sure take closer @ following pages. bootstrap has great documentation page.

flex , spacing
