Changing style?

[ilixn]

Hello !
I really love your project, but i would like to make the footer work. Currently the "footer" file is totally commented, and the footer isn't placed very well when "activated". To make it work, i think i must deactivate the effect that makes the cards go on top of the other when scrolling. This is very nice, but if this effect isn't activated and the cards scroll normally, i think the footer will work. So that's my question: How do you deactivate this effect and make the cards "fixed" on the page (like the text in "about") ?
I hope i'm clear, but i'm not English so excuse my bad English... ;)

Thanks !
