How To Create a Tooltip
Add the data-toggle=”tooltip” attribute to an element in order to produce a tooltip.
To provide the text that should appear inside the tooltip, use the title attribute:
<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>
Note: To initialize a tooltip, select the desired element and invoke the tooltip() function using jQuery.
All of the document’s tooltips will be enabled by the code below:
Example
<script>window.addEventListener('DOMContentLoaded', function() {
$(document).ready(function(){
$('[data-toggle="tooltip"]').tooltip();
});
});</script>
Positioning Tooltips
The tooltip will always show up above the element.
To position the tooltip at the top, bottom, left, or right of the element, use the data-placement attribute:
Example
<a href="#" data-toggle="tooltip" data-placement="top" title="Hooray!">Hover</a>
<a href="#" data-toggle="tooltip" data-placement="bottom" title="Hooray!">Hover</a>
<a href="#" data-toggle="tooltip" data-placement="left" title="Hooray!">Hover</a>
<a href="#" data-toggle="tooltip" data-placement="right" title="Hooray!">Hover</a>
