How to animate elements onload?

I am using Fixer theme as a base and I would like to have an effect of elements sliding in when page is scrolled down just as here http://www.pradniknowy.pl/inwestycja/inwestycja.
Can I achieve it somehow using Upfront? Or in any other way (I used to use VC with Ultimate Addons for that but I'd like to give Upfront a try)

Best regards
Paulina
