Tooltips
These are useful for showing unobtrusive helper content.
<tooltip text="Add to content to library"> <button class=" btn btn-dark" style="padding:6px;"> <div class="h-a v-a"> <i data-feather="command" style="height:15px; width:15px;"></i> </div> </button> </tooltip>
Note this requires javascript (Vuejs 2.0)
