Intro.js

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

Where to get

You can obtain your local copy of Intro.js from:

1) This github repository, using git clone https://github.com/usablica/intro.js.git

2) Using bower bower install intro.js --save

3) Using npm npm install intro.js --save

4) Download it from CDN (1, 2)

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!'></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'.

Using templates

IntroJS provides awesome templates and we are trying to update and add more templates for next versions. You can browse all templates here: https://github.com/usablica/intro.js/wiki/IntroJs-templates

In order to use templates, all you need to do is appending the template stylesheet to your page, after IntroJS CSS file:

<!-- Add IntroJs styles -->
<link href="../../introjs.css" rel="stylesheet">

<!-- Add Nazanin template -->
<link href="../../themes/introjs-nazanin.css" rel="stylesheet">
