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. Use introjs-rtl.min.css for Right-to-Left language support.

CDN hosted files are available at jsDelivr (click Show More) & cdnjs.

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>

See all attributes here.

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'.
