CSS Question

AngularJS tooltip without bootstrap?

I'm fairly new to AngularJS, and working on a project that is very restrictive towards external dependencies; in fact, Bootstrap is ruled out, and yet, I have to implement a "tooltip" directive.

I'm trying to do it using mouseenter and mouseleave events, but I wonder how can I use the directive's own attribute as the tooltip's content?

It'd be used like this:

<a id='someLink' my-tooltip='The content that I want to show'>Trigger</a>

Being quite green on UI development, can anyone tell me how I could add the necessary HTML/CSS to make this work through the directive?

app.directive("tooltip", function () {
  return {
    link: function (scope, element, attrs) {

        $(element).on("mouseover", function () {
            $(this).append("<span>"+ attrs.tooltip +"</span>");

        $(element).on("mouseout", function () {

        scope.$on("$destroy", function () {
