JS Tooltip (tooltip.js)

The Tooltip plugin is small pop-up box that appears when the user moves the mouse pointer over an element.

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

// Select a specified element

Tooltip Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-placement="".

Name Type Default Description Try it
animation boolean true

Specifies whether to add a CSS fade transition effect when showing and hiding the tooltip

  • true - Add a fading effect

Try it
container string, or the boolean false false Appends the tooltip to a specific element.
Example: container: 'body'
Try it
delay number, or object 0 Specifies the number of milliseconds it will take to show and hide the tooltip.

To specify a delay for showing and another one for hiding, use the object structure:

delay: {show: 500, hide: 100} - which will take 500 ms to show the tooltip, but only 100 ms to hide it
Try it
html boolean  false Specifies whether to accept HTML tags in the tooltip:
  • true - Accept HTML tags
  • false - Do not accept HTML tags

  • "top" - Tooltip on top

Try it
selector string, or the boolean false false Adds the tooltip to a specified selector Try it
