Intro.js

Better introductions for websites and features with a step-by-step guide for your projects.

How to use

Intro.js can be added to your site in three simple steps:

1) Include intro.js and introjs.css (or the minified version for production) in your page.

2) Add data-intro and data-step to your HTML elements.

For example:

<a href='http://google.com/' data-intro='Hello step one!' data-step='1'></a>

Optionally you can define data-position attribute to define the position of tooltip with values top, right, left and bottom. Default value is bottom.

3) Call this JavaScript function:

introJs().start();

Optionally, pass one parameter to introJs function to limit the presentation section.

For example introJs(".introduction-farm").start(); runs the introduction only for elements with class='introduction-farm'.
