well - in looking at it again...
it appears - the PUBLISHED site.... the paragraphs do not fade in the way you want.
and the text in the 3rd section does not appear at all
see video: http://quick.as/yvdpC5Wp
in your project... I changed the 2nd section to yellow - to see it better - and also changed the paragraph text.
I also think you have an issue with the interactions. You have 1 interaction for all the sections - and it controls all the paragraphs.
So if you scroll into a section - all the paragraphs - in all section "fade-in".
I changed fade-in to move to origin. On init and scroll-out I added move left 200.
I will have build my own project using fullpage to determine more.
but I cannot publish your site - that's why I have to build my own
- and I have 6 sites under development right now (February) with 10 more due in March.
I'm not sure if I can take the time to build a test site for you.
I think the problem is in the way you are calling your interactions.
And all your paragraphs are class the same name.
So all paragraphs are affected the same way.
Can you clone the project ? That way I can just add it into my library / dashboard and work from there.
Otherwise. like I said... time is very limited.
