<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>"> Tooltip with HTML </button>

You must only incorporate tooltips to HTML components that are certainly interactive and ordinarily keyboard-focusable ( like links or form controls). Although arbitrary HTML elements ( just like
<!-- HTML to write --> <a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a> <!-- Generated markup by the plugin --> <div class="tooltip tooltip-top" role="tooltip"> <div class="tooltip-arrow"></div> <div class="tooltip-inner"> Some tooltip text! </div> </div>
