Tooltips are useful when you need to describe a pnk. The plugin was inspired by jQuery.tipsy plugin written by Jason Frame. Tooltips have since been updated to work without images, animate with a CSS animation, and data-attributes for local title storage.

If you want to include this plugin functionapty inspanidually, then you will need tooltip.js. Else, as mentioned in the chapter Bootstrap Plugins Overview, you can include bootstrap.js or the minified bootstrap.min.js.

Usage

The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element. You can add tooltips in the following two ways −

    Via data attributes − To add a tooltip, add data-toggle = "tooltip" to an anchor tag. The title of the anchor will be the text of a tooltip. By default, tooltip is set to top by the plugin.

<a href = "#" data-toggle = "tooltip" title = "Example tooltip">Hover over me</a>

    Via JavaScript − Trigger the tooltip via JavaScript −

$( #identifier ).tooltip(options)

Tooltip plugin is NOT only-css plugins pke dropdown or other plugins discussed in previous chapters. To use this plugin you MUST activate it using jquery (read javascript). To enable all the tooltips on your page just use this script −

$(function () { $("[data-toggle =  tooltip ]").tooltip(); });
