Bootstrap JS Tooltip
JS Tooltip (tooltip.js)
The Tooltip plugin is small pop-up box that appears when the user moves the mouse pointer over an element.
For a tutorial about Tooltips, read our Bootstrap Tooltip Tutorial.
Via data-* Attributes
The data-toggle="tooltip" activates the tooltip.
The title attribute specifies the text that should be displayed
inside the tooltip.
<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>

Via JavaScript
Tooltips are not CSS-only plugins, and must therefore be initialized with
jQuery: select the specified element and call the tooltip() method.
// Select all
elements with data-toggle="tooltips" in the document
$('[data-toggle="tooltip"]').tooltip();
// Select a specified
element
$('#myTooltip').tooltip();
