Simple overlay instructions for your apps.



Simple overlay instructions for your apps.

Check out a demo.

Chardin.js is a jQuery plugin that creates a simple overlay to display instructions on existent elements. It is inspired by the recent Gmail new composer tour which I loved.

Jean-Baptiste-Siméon Chardin


Simple! Fork this repo or download chardinjs.css and chardinjs.min.js and add the following assets to your HTML:

<link href="chardinjs.css" rel="stylesheet">
<script src="chardinjs.min.js"></script>

Installing in the rails asset pipeline (optional)

There's a chardinjs-rails gem.

Building (optional)

If you choose to fork the repo you can build the assets running

rake compile

Adding data for the instructions

Add the instructions to your elements:

data-intro: Text to show with the instructions
data-position: (left, top, right, bottom), where to place the text with respect to the element

<img src="img/chardin.png" data-intro="An awesome 18th-century painter, who found beauty in everyday, common things." data-position="right" />


Once you have your elements ready you can show instructions running


If you would rather run ChardinJs confined to a particular container (instead of using the whole document) you can change body to some other selector.


You may also refresh instructions overlay any time to reflect whatever changes happened to the underlying page elements since the instructions overlay has been displayed.

var chardinOverlay = $('body').chardinJs('start');



Start ChardinJs in the selector.


Toggle ChardinJs.


Make your best guess. That's right! Stops ChardinJs in the selector.



Triggered when chardinJs is correctly started.


Triggered when chardinJs is stopped.
