You can use only CSS for building Tooltips, this way:
CSS 
*{
    font-family: Arial, sans-serif;
}
div > .tooltip, li > .tooltip, a > .tooltip, span > .tooltip {
  opacity: 0;
  visibility: hidden;
  -webkit-transition: 0.3s;
  -moz-transition: all 0.3s;
}
  div:hover > .tooltip, li:hover > .tooltip, a:hover > .tooltip, span:hover > .tooltip,
  a .tooltip:hover, span .tooltip:hover, li .tooltip:hover, div .tooltip:hover {
    opacity: 1;
    visibility: visible;
    overflow: visible;
    margin-top: -40px;
    display: inline;
    margin-left: -40px;
    -webkit-transition: 0.3s;
    -moz-transition: all 0.3s;
  }
.tooltip {
  background: #3378C1;
  color: #fff;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  -o-border-radius: 5px;
  border-radius: 5px;
  padding: 10px;
  margin-left: -40px;
  position: absolute;
  font-family: Arial;
  font-size: 12px;
  text-decoration: none;
  font-style: normal; 
  z-index: 10;  
}
    .tooltip:before { /* Triangle */
      content: "";
      background: #3378C1;
      border: 0; 
      width: 10px;
      height: 10px;
      margin-left: 5px;
      margin-top: 20px;
      display: block;
      position: absolute;
      -webkit-transform: rotate(-45deg);
      -moz-transform: rotate(-45deg);
      -o-transform: rotate(-45deg);
      transform: rotate(-45deg);
      display /*\**/: none\9;
      *display: none !important;
      *display: none;
    }
**HTML**
<html lang="pt-br">
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<br>
<br>
  <p>Este é exemplo demonstrativo de utilização de 
<a href="#"><strong>Tooltips</strong>
<span class="tooltip">
  Clique aqui e abra este link 
</span></a> 
e com isto fornecer mais uma ferramenta para seu website.</p>
Take a look at the working example here.
							
							
						 
Modify the plugin so that it uses another attribute other than
titlewould be a viable solution?– Guilherme Bernal
I thought about it. But at first I don’t know if it would be the most recommended. It’s the Bootstrap Popover.
