Sticky-stack kaarten

Cards pin and scale down as the next slides over.

How to use it

Paste the HTML where the scroll effects should appear. Include the script tags at the top once per page.
Add the CSS to your stylesheet. All classes are prefixed, so nothing clashes with your own styles.
Add the JavaScript and call init() with the element that contains the HTML.
