A tooltip is a small pop-up which appears when a cursor is positioned over an icon, image, hyperlink or other element in a graphical user interface. It is small, boxed text message which provides some detail about the text when the mouse pointer hovers over given text. Tooltips are helpful for new users because they enable the user to learn about each object by hovering their mouse over them.

We can create tooltips by using following two ways:
- Via Data Attributes
- Via JavaScript
Bootstrap Tooltip via Data Attributes
We can create bootstrap tooltip by using the attribute data-toggle=”tooltip” within the anchor element. For instance, if we want to display tooltip on left side, then we use the attribute data-placement=”left” and similarly for right, top and bottom positions. The following is an example:
<!DOCTYPE html>
<head>
<title>Bootstrap Example</title>
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script>
$(function(){
$("[data-toggle='tooltip']").tooltip();
});
</script>
</head>
<body>
<div class="container">
<h2>Tooltip for Buttons</h2><br>
<button type="button" class="btn btn-default" data-toggle="tooltip"
data-placement="left" title="Left Tooltip">Tooltip on left</button>
<button type="button" class="btn btn-default" data-toggle="tooltip"
data-placement="top" title="Top Tooltip">Tooltip on top</button>
<button type="button" class="btn btn-default" data-toggle="tooltip"
data-placement="bottom" title="Bottom Tooltip">Tooltip on bottom</button>
<button type="button" class="btn btn-default" data-toggle="tooltip"
data-placement="right" title="Right Tooltip">Tooltip on right</button>
</body>
</body>
</html>
Bootstrap Tooltip via JavaScript
It’s also possible to display tooltip on top, left, right and bottom sides of an element by using javascript code as shown in the below example:
<!DOCTYPE html>
<head>
<title>Bootstrap Example</title>
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script>
$(document).ready(function(){
$("#top").tooltip({
placement:'top'
});
$("#right").tooltip({
placement:'right'
});
$("#bottom").tooltip({
placement:'bottom'
});
$("#left").tooltip({
placement:'left'
});
});
</script>
</head>
<body>
<div class="container">
<h2>Tooltip using JavaScript</h2><br>
<button type="button" class="btn btn-default" data-toggle="tooltip" id="top"
data-placement="top" title="Top Tooltip">Tooltip on top</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" id="right"
data-placement="right" title="Right Tooltip">Tooltip on right</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" id="bottom"
data-placement="bottom" title="Bottom Tooltip">Tooltip on bottom</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" id="left"
data-placement="left" title="Left Tooltip">Tooltip on left</button>
</div>
</body>
</body>
</html>
