How to setup the parallax effect
The class that triggers the parallax effect is ".paraxify" and can be used to any other elements where you want to add a parallax effect.
<div class="parallax paraxify " style="background-image: url(../images/section2.jpg);" data-speed="0.5" > </div>
The code for js that changes the speed of parallax is found in app/js/src/script.js
