The tooltips appearance as well as activity has stayed practically the identical in both the Bootstrap 3 and 4 versions since these actually perform work really effectively-- absolutely nothing much more to become called for from them.
One approach to activate all of tooltips on a page would undoubtedly be to pick them through their
$(function () $('[data-toggle="tooltip"]').tooltip() )
4 opportunities are provided: top, right, bottom, and left coordinated.

<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top"> Tooltip on top </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right"> Tooltip on right </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom"> Tooltip on bottom </button> <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left"> Tooltip on left </button>

The tooltips need to be exactly this-- quick significant ideas-- positioning far too much details might just even confuse the site visitor instead of support getting around.
