Hello,
In this demo, http://theme.co/x/demo/integrity/1/ you can see how the different pieces keep appearing. Are all of those made with Slider Revolution?
Also, you can see some of the backgrounds moving when you scroll down. How is that done?
The first effect is the fade in effect. You can find it in the documentation for several elements you can control from where it should slide/fade in. Most of the sliders are made with revolution slider or our slider shortcode. The moving background effect is called parallax you can turn it on when using a content band.
